Evaluate the complete customer-contact workflow
Start with the sales motion
Separate scheduled account conversations from high-frequency outbound prospecting. Record who initiates calls, where contact records live and how follow-up work is assigned. Shared outbound identity, personal direct numbers and inbound callbacks create different requirements. A missed callback should reach an accountable person or team instead of disappearing into an individual mailbox during absence.
Features that matter
Evaluate click-to-call, contact lookup, accurate activity logging, transfer and callback ownership. Test the integration against your exact CRM edition and permission model. Ask whether a logged call represents an attempted, connected or completed conversation, and how duplicate contacts are handled. Treat automatic recording and transcription as separate capabilities with their own access and retention decisions.
Network and capacity planning
Estimate simultaneous conversations during an active calling session rather than dividing daily calls by working hours. Include consultations and transfers in a realistic pilot. Check upload headroom and headset performance while users also run their normal browser and CRM workloads. Record call timestamps so a reported audio problem can be correlated with provider and network evidence.
Endpoints for sustained calling
A desktop client may suit a CRM-heavy workflow, while a desk phone can provide reliable physical controls. Select headsets for fit, microphone placement and compatible call controls. Pilot the actual client, operating system and headset combination. Mobile callbacks need a clear business identity and a route back to the shared customer record.
Hosted or self-hosted?
Hosted integrations can shorten implementation if their supported workflow matches yours. Self-hosting can support tailored call handling but requires someone to maintain authentication, APIs, event mapping and upgrades. Price the integration’s operating work, not just the phone subscription. Keep a workable manual process for periods when the CRM connection is unavailable.
Mistakes and buyer questions
Do not treat an integration logo as proof of bidirectional synchronization or a recording feature as a complete governance policy. Ask about API limits, data export, user mapping, failure alerts and deletion behavior. Have the buyer and administrator agree on permitted outreach and recording practices for their operating locations before enabling automation; the phone system alone does not decide those obligations.
