Mark, I thought I would also mention that I am still having similar issues even after updating to the latest Asterisk, Zaptel and Libpri. Although I am using a Sangoma, we have similar symptoms with a restart fixing it. I am starting to wonder if I must go back to a Digium card. We originally switched away from the Digium TE110 because of interrupt issues, I think that the interrupt issue has been remedied now. _____

Does that sound possible? I've never had problems with the circuit until I moved it from a standard digium PRI card to a TDMoE device. Also, if I restart asterisk, all the b-channels come back. Thoughts?

You probably have noise on your T1 circuit, which is causing the PRI signalling to become corrupt. If this continues, expect that the T1 circuit will go down from time to time, for a few seconds each time. Your solution is to call your telco and ask for a loopback test. -- Tilghman _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users No virus found in this incoming message.
