Customer context: The customer wants to know if it's possible to connect a phone number from any VoIP provider to LiveAgent.
Customer question: Can I connect a phone number from any VOIP provider to LiveAgent?
Solution: Yes, you can connect a phone number from any VoIP provider to LiveAgent as long as the provider supports SIP trunks, since integration is made via SIP trunk only. You will need to purchase a number from your chosen VoIP provider, as LiveAgent does not provide or sell phone numbers. It is not possible to integrate phone numbers from providers that do not support SIP trunks. You can view a list of available VoIP providers on the LiveAgent integrations page, but you can also connect numbers from providers not listed by using the General method.
