  hi all, i'm ryan and i've just joined this mailing list. i've tried installing chan_ss7 version 0.8.1 on my two servers. followed the step-by-step setup to test e1 cards with ss7 signalling that i found at voip-info.org. i was hoping somebody can help me with my problem here.
  i've setup a master server with te411p in it and a slave with te110p inside it. used centos 4.2 x64 and asterisk 1.2.5 and zaptel 1.2.4. my problem is when i dial i can't hear a ringing tone from my handset but the dialed fone rings. at first i thought of the codec, btw i'm using alaw as my primary codec, tried using ilbc but i'm having echo at the callee side. also that when the call is going on for already about past 5 minutes, the audio deteriorates, it becomes choppy and i'm having these debug messages coming out from my master server.
