Why Does a VoIP Caller Hear Silence Before the Call Connects?

Silence before connection can be caused by call progress signaling, early media, provider routing, or an endpoint expectation mismatch. It may affect only certain destinations.

What to check

Compare internal and external call routes, destination carrier, progress tones, SIP responses, and timestamps. Test with a different endpoint and network where possible.

Recommended next step

Trace the call path with the provider and correct the signaling or media behavior. Informatix Systems can troubleshoot VoIP call setup and routing.
