Hi guys, I'm using SIP phones with Asterisk 1.2 and going fine, most of the time. However, when the duration of a call is longer than 20minutes I often stop hearing the other party, but that one keeps most of the time hearing me. Does any of you know of this or similar problems? Thing is that I'm connected to the Asterisk over VPN tunnel, but how sensitive is the SIP protocol to a short glitches in connection? BR.
