For a real estate agent, the implementation brief should explain which number appears, where calls arrive, and what happens when tracking fails. Use the [call-tracking provider comparison](/articles/compare-call-tracking-for-agent-website-inquiries) to shortlist software. This brief covers the number replacement rules your chosen provider must demonstrate. The proposed checks below have not been run on your website. ## What does dynamic number insertion change? It changes the displayed tracking number according to the configured source or visitor rule. Twilio describes associating phone numbers with advertising sources and forwarding incoming calls. That explains the attribution mechanism, rather than proving a particular website works. [Twilio definition, checked 2026.10.22](https://www.twilio.com/docs/glossary/what-is-dynamic-number-insertion). Start your brief with the question the attribution should answer, such as which campaigns generated received seller inquiries. ## How is source tracking different from visitor tracking? Source tracking associates a number with a campaign; visitor tracking associates a number with an individual website visitor. CallRail describes those approaches separately. Ask the provider which approach your proposed installation uses. [CallRail attribution description, checked 2026.10.22](https://www.callrail.com/call-tracking/attribution). Keep the selected method beside your report definition. Do not compare channel totals produced under different attribution methods without identifying that difference. ## Which phone number should remain the website baseline? Specify the approved business number as the baseline before defining replacements. Record its owner, receiving destination, displayed format, and phone-link value. Have the developer show the baseline in the original page content. This is a proposed continuity requirement. Confirm how your chosen implementation preserves it before accepting a tracking script. ## What belongs in the number-replacement map? Record the source condition, affected page elements, tracking number, receiving destination, and fallback behavior. Ask the developer to complete this table with your verified values. | Field | Value to supply | | --- | --- | | Trigger | Exact campaign or visitor rule | | Page elements | Header, footer, contact card, and phone button | | Tracking destination | Approved receiving phone route | | No match | Baseline behavior | | Failure owner | Person responsible for restoring calls | ## How should competing source rules be handled? Require a written precedence rule. Ask which condition wins when a campaign parameter and another source signal both apply. Keep unmatched traffic in an explicit category. Use controlled visits to check the proposed rule order. Record the source inputs and observed number. Do not infer precedence from a dashboard label alone. ## Should every phone number on the page be replaced? Replace only the contact elements included in the approved scope. Exclude numbers that identify another service or belong in quoted source material. Give the developer an explicit selector inventory. Check repeated contact cards, mobile menus, and property-page components. Record every excluded number so later maintenance does not broaden the replacement accidentally. ## What should happen to tap-to-call links? Require the dialed destination to match the approved number shown beside it. Test the visible text and link separately on each affected template. Save the displayed value, the link target, and the receiving-call result. Treat a changed label with an unchanged dialing destination as a failed configuration check. ## What happens when the tracking script does not load? Require an agreed fallback contact route to remain usable. Have the maintainer demonstrate that condition in a test environment by blocking the tracking request. Record the resulting number and complete a permitted call test. Keep a separate email or inquiry link available when that alternative belongs in the website brief. ## What should happen before a replacement finishes loading? Ask the developer to demonstrate the initial page state and the completed state. Define acceptable contact behavior during loading, including what a quick phone-button tap reaches. Treat slow loading as a separate scenario from total script failure. Keep both observations in the acceptance record instead of assuming the finished page represents every visit. ## How should repeat visits be tested? Write a repeat-visit scenario and ask the provider to explain its expected attribution. Include a saved tracking number and a later direct return where relevant. Keep the expected behavior beside the observed result. Mark the source UNRESOLVED when the available records cannot distinguish the visits. Do not reconstruct a missing journey from memory. ## Can a tracking number follow someone across pages? Some implementations support that behavior. CallRail describes visitor tracking as carrying the visitor's assigned number through page navigation and return visits. Confirm the behavior in your selected account and configuration. [CallRail visitor-tracking description, checked 2026.10.22](https://www.callrail.com/call-tracking/attribution). Test navigation from a seller resource to the contact page. Record the number on both pages and the resulting call. ## How should number-pool limits be specified? Ask the provider to size the pool against your expected traffic and explain what happens when available numbers run out. Twilio describes recycling unused numbers as part of dynamic number insertion. [Twilio pooling explanation, checked 2026.10.22](https://www.twilio.com/docs/glossary/what-is-dynamic-number-insertion). Leave pool size and overflow behavior UNRESOLVED until the provider documents your configuration. Do not invent a traffic-to-number ratio. ## Should public business profiles use the rotating number? Keep profile-number changes outside the initial website test. Maintain a baseline identity sheet and have the responsible reviewer approve any public contact change separately. Ask the provider how website substitution interacts with your existing profile configuration. This brief sets a review boundary; it does not establish any platform's profile-number policy. ## How should embedded listing searches be handled? Inventory the embedded search and its contact controls separately. Ask the provider which elements its installation can reach, then verify those elements in the agreed test environment. Leave an embedded number unchanged until its owner authorizes the work. Keep a clear route back to the real estate agent's own contact page. ## What proves that a call reached the intended recipient? A matched receiving record proves the delivery check. Coordinate a permitted test with the receiving person and identify it as a test. Retain the time, page, displayed number, dialed number, answer result, and receiver confirmation. A reported phone-button click alone does not complete this proposed call-delivery check. ## What proves that source attribution worked? Match the controlled visit and received call with the provider's source record. Save the campaign link and observed attribution rule alongside the result. Test each source you intend to compare. Keep a failed or missing attribution result open even when the receiving phone rang. Delivery and attribution need their own evidence fields. ## How should missed calls appear in the handoff? Specify the missed-call destination and responsible follow-up person. Have the receiving team demonstrate how it finds the test record and determines the next action. Keep answering hours, voicemail, and backup coverage in the phone brief. Do not publish a response-time promise until the responsible real estate agent approves it. ## Does installing number insertion require call recording? Treat recording as a separate proposed feature. Ask the provider whether attribution can operate under your chosen recording settings. Leave the account-specific answer UNRESOLVED until confirmed. Have the responsible professional review any recording proposal before activation. Keep notices, access, and retention decisions out of the number-swap acceptance claim. ## What should the reporting handoff contain? Request the source definition, number inventory, receiving destinations, test records, and export instructions. Separate calls, repeat callers, and verified buyer or seller inquiries in your reporting brief. Record unknown sources explicitly. Ask the receiving person to classify inquiry purpose rather than treating every tracked call as a new business opportunity. ## What costs need confirmation before installation? Request a written quote covering numbers, usage, installation, support, exports, and cancellation. Leave the total UNRESOLVED until those items are specified for your scope. Ask how changes in traffic or number requirements affect billing. This article supplies no provider price and assumes no included integration. ## What should happen when the provider is replaced? Write the exit sequence before installation. Assign responsibility for number continuity, records export, replacement contact tests, and removal of obsolete website code. Obtain the provider's current transfer and cancellation instructions. Confirm a working contact route before retiring the old configuration. Preserve the number map with the website handoff. ## What should a real estate agent put in the website brief? Bring the affected pages, baseline number, desired source rules, receiving destination, and fallback requirement. Include the agreed controlled-call tests and the person who can approve them. Use the [real estate website scope](/for/real-estate) to connect that phone work to the rest of the inquiry path. Require the approved configuration and evidence to stay with your website files. - [Add Acuity Scheduling to a real estate consultation page](/articles/acuity-agent-consultation-website-integration) - [Calendly reminders for real estate consultations: configure and verify](/articles/calendly-agent-consultation-reminders) - [Set Calendly buffers around real estate consultations](/articles/calendly-buffer-time-agent-consultations) ## Related: Real estate - [Add Acuity Scheduling to a real estate consultation page](/articles/acuity-agent-consultation-website-integration) - [Calendly reminders for real estate consultations: configure and verify](/articles/calendly-agent-consultation-reminders) - [Set Calendly buffers around real estate consultations](/articles/calendly-buffer-time-agent-consultations) ---- ```text .|########||. .|########||. .|########||. |##||. .||##|. |##||. .||##|. |##||. .||##|. |#|. .|#|. |#|. .|#|. |#|. .|#|. |#| |#| |#| |#| |#| |#| .#| |#. .#| |#. .#| |#. .#. .#| .#. .#| .#. .#| |#. .#| |#. .#| |#. .#| |# ...... #| |# ...... #| |# ...... #| .# ||#########| #| .# ||#########| #| .# ||#########| #| .#. |######||######|. .#. .#. |######||######|. .#. .#. |######||######|. .#. #. .##|###|##|#|######| .# #. .##|###|##|#|######| .# #. .##|###|##|#|######| .# || |##|#||||||||||||#||#| || || |##|#||||||||||||#||#| || || |##|#||||||||||||#||#| || # |#||||||||||||||||||||#| #. # |#||||||||||||||||||||#| #. # |#||||||||||||||||||||#| #. || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || # .#||||||||||||||||||||||||#| # # .#||||||||||||||||||||||||#| # # .#||||||||||||||||||||||||#| # || ....|||#||||||##|#|||#|#||##||||....|. || || ....|||#||||||##|#|||#|#||##||||....|. || || ....|||#||||||##|#|||#|#||##||||....|. || #. . ....|# ....#||| ||| .#||| ....#. .# #. . ....|# ....#||| ||| .#||| ....#. .# #. . ....|# ....#||| ||| .#||| ....#. .# # . ||||#| .#####|| . .#| .#||| ||||# #. # . ||||#| .#####|| . .#| .#||| ||||# #. # . ||||#| .#####|| . .#| .#||| ||||# #. .| ||||| #. |#|||||. || #. |#||. .||||| || .| ||||| #. |#|||||. || #. |#||. .||||| || .| ||||| #. |#|||||. || #. |#||. .||||| || || |.... #. ....|#. |. ...|. ....|| || || |.... #. ....|#. |. ...|. ....|| || || |.... #. ....|#. |. ...|. ....|| || #. .||||||##||||||##||####|||||||#||||||#| .# #. .||||||##||||||##||####|||||||#||||||#| .# #. .||||||##||||||##||####|||||||#||||||#| .# # .||####|###########################|. # # .||####|###########################|. # # .||####|###########################|. # # .#||||||.#.|| # |. ..# #| #|||||#| # # .#||||||.#.|| # |. ..# #| #|||||#| # # .#||||||.#.|| # |. ..# #| #|||||#| # # .#|||||| .. |# ## |#| ...#|#|||#| # # .#|||||| .. |# ## |#| ...#|#|||#| # # .#|||||| .. |# ## |#| ...#|#|||#| # # .#|||#|# .# .#| #| ##|.#..#|||||#| # # .#|||#|# .# .#| #| ##|.#..#|||||#| # # .#|||#|# .# .#| #| ##|.#..#|||||#| # # .#||||||############|######|||||#| # # .#||||||############|######|||||#| # # .#||||||############|######|||||#| # # |...||#||||||#||||#|#||||||#|||||#||| |.| # # |...||#||||||#||||#|#||||||#|||||#||| |.| # # |...||#||||||#||||#|#||||||#|||||#||| |.| # #. .. ||||# .|||##|. |#| .|| || .|||#. #| # .# #. .. ||||# .|||##|. |#| .|| || .|||#. #| # .# #. .. ||||# .|||##|. |#| .|| || .|||#. #| # .# || | ...|| ...##| | #| .|. |. ##### .. .| || || | ...|| ...##| | #| .|. |. ##### .. .| || || | ...|| ...##| | #| .|. |. ##### .. .| || || ||||| || ||||#| . |. |. |#. ||||| |#| || || || ||||| || ||||#| . |. |. |#. ||||| |#| || || || ||||| || ||||#| . |. |. |#. ||||| |#| || || .# |.....#|....|#.||||.|||##.|#|....||.#||.#. #. .# |.....#|....|#.||||.|||##.|#|....||.#||.#. #. .# |.....#|....|#.||||.|||##.|#|....||.#||.#. #. #.|||||||#############################| ||| .# #.|||||||#############################| ||| .# #.|||||||#############################| ||| .# || ##||#||#||||||#||#||#||#||##. || || ##||#||#||||||#||#||#||#||##. || || ##||#||#||||||#||#||#||#||##. || # .#|||||||||#||#|||||||||||#| # # .#|||||||||#||#|||||||||||#| # # .#|||||||||#||#|||||||||||#| # || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || .# |#||||||||||||||||||||#| #. .# |#||||||||||||||||||||#| #. .# |#||||||||||||||||||||#| #. || |#||||||||||||||||||#| || || |#||||||||||||||||||#| || || |#||||||||||||||||||#| || #. .######|#|#########| .# #. .######|#|#########| .# #. .######|#|#########| .# .#. |#####||||#####| .#. .#. |#####||||#####| .#. .#. |#####||||#####| .#. |# ||########|| #. |# ||########|| #. |# ||########|| #. |# ...... #| |# ...... #| |# ...... #| |#. .#| |#. .#| |#. .#| |#. .#. |#. .#. |#. .#. .#| |#. .#| |#. .#| |#. |#| |#| |#| |#| |#| |#| .|#|. .|#|. .|#|. .|#|. .|#|. .|#|. |##||. .||##| |##||. .||##| |##||. .||##| .||########||. .||########||. .||########||.
