I would like to know, if it is possible to integrate SUITECRM with VoIP, so that inbound calls would access CRM to provide information about the caller; on the other sense that we could generate outbound calls by selecting a customer from CRM.
Please check out RT Telephony (RT Telephony | SuiteCRM Module) on the Suite Store. It provides voice as well as SMS capabilities for both inbound and outbound communication. It requires a Twilio account to integrate with your CRM, but it provides a smooth and hassle free experience once you have set it up.
