CRM and ERP telephony integration means data flows both ways between your calls and your business systems. When a call comes in, the phone system queries your CRM to identify the customer and adapt the journey. When it ends, the call is logged automatically with its duration, outcome and, if you want, a transcript or summary.
The result: agents who know who is calling before they pick up, IVRs and voicebots that answer with real information, and a complete customer history with no manual data entry.
What integration makes possible
- Caller identification: match the phone number to a customer record, or identify the caller by account, policy or order number entered on the keypad or spoken.
- Screen pop: open the customer record on the agent’s desktop as the call is presented.
- Automatic call logging: create a call activity in the CRM with timestamp, agent, queue, duration, outcome and a link to the recording.
- Data-driven self-service: balance, order status, next appointment or open invoice, delivered directly by the IVR or voicebot.
- Write-back actions: book an appointment, update an address, open a ticket or record a payment, with the right controls in place.
- Data-based routing: prioritize customers with an open case, route to their assigned account manager, respect their preferred language.
Our secure payment voicebot case study shows the principle in practice: a voicebot integrated with the billing system and CRM cut costs by 65% and divided handling time by three.
Systems we integrate
| System type | Examples | Common uses |
|---|---|---|
| CRM | Salesforce, HubSpot, Microsoft Dynamics | identification, screen pop, call logging |
| ERP | SAP, industry ERPs | orders, billing, inventory |
| Scheduling and line-of-business tools | booking software, ticketing tools | booking, confirmation, reminders |
| Databases | PostgreSQL, MySQL, SQL Server | in-house apps, history |
We are not a partner or reseller of any of these vendors. We integrate what you already use, through their documented APIs.
How we deliver it
A connector between telephony and your systems
Rather than calling the CRM directly from the dialplan, we put a dedicated integration service in between. On the telephony side, it is called through Asterisk AGI for simple lookups or through ARI for application-driven journeys. On the business side, it talks to your REST or SOAP APIs, your webhooks or, as a last resort, your database.
This separation has three benefits: telephony stays independent from the CRM, credentials are managed in one place, and switching CRMs does not mean rebuilding your call flows.
Performance and fallback
During a live call, latency matters. We set strict timeouts, cache data that rarely changes and always define a default path: if the CRM does not answer, the call is routed normally without enrichment.
Data security
Encrypted connections, least-privilege service accounts, access logging and particular care with sensitive data such as payments or health information. For payments, we design flows that limit exposure of card data, as we did for our secure payment voicebot project. Exact requirements depend on your regulatory context.
Common integration pitfalls
Most telephony integration problems are not technical failures but design gaps. We address them up front:
- Unreliable phone number matching: numbers stored in different formats, shared lines, or several contacts on the same number. We normalize numbers (E.164) and define what happens when there are zero or multiple matches.
- API rate limits: some CRMs cap requests per minute or per day. Peak call volume must fit within those limits, which sometimes calls for caching or batched logging.
- Duplicate or incomplete call records: transfers and callbacks can create several activities for one conversation. We define a clear rule for how one call is represented in the CRM.
- Permissions that are too broad: a service account with admin rights is a risk. We request only the objects and fields actually needed.
How a project runs
- Inventory: systems in scope, data needed at each step of the call, available APIs and their limits.
- Data exchange specification: what to read, what to write, when, and with which permissions.
- Connector development and testing against a staging instance of your CRM or ERP.
- Pilot on one queue or call flow, checking the quality of logged data.
- Rollout and monitoring: extension to other flows and ongoing tracking of integration errors.
What to expect and prerequisites
What you get: a documented connector, call journeys enriched with your data, reliable call history in your CRM and dashboards showing integration errors.
Prerequisites:
- API access to your systems (keys or service accounts), ideally with a test environment;
- a clear customer identification rule (phone number, account number, etc.);
- a business data owner to validate what is read and written;
- a phone system reachable over SIP, or an interconnection we define together.
This kind of integration often sits on top of a telephony orchestration layer and is especially valuable in financial services, where identification and traceability are central.
