Incoming call using SIP gateway noisy because of blow
When passing incoming call to a Cisco IP throught a SIP gateway and CCM 4.1, I hear a loud blow on the caller phone side. And when passing the same call using the same gateway but set with H.323, I have a clear communication. What can be the reason of that ? nb: I used G711 Alaw for both.- ophiro2
