My sip phones are connected to asterisk PBX 1.2.4. The PBX is connected to the provider through IAX2 connection. Sometimes randomly the voice is stopped and both caller and called don't hear the other's voice. During this silence period Asterisk is not logging any errors. This happen on incoming calls too, and incoming calls are through ISDN BRI lines Any idea? Thanks -------------- next part -------------- An HTML attachment was scrubbed...
