Hello! As the subject states, I'm experiencing an odd issue with one of my client's systems. We're running a Sangoma A400D card with 8 FXO channels. The POTS line on channel 5, whenever called, generates the following message on the asterisk console: Apr 29 10:35:08 WARNING[16927]: chan_zap.c:3926 zt_handle_event: Ring/Off-hook in strange state 6 on channel 5 Apr 29 10:35:09 WARNING[16927]: chan_zap.c:3926 zt_handle_event: Ring/Off-hook in strange state 6 on channel 5 Eventually, the call will be "answered" and passed to the inbound context (a ring group). When anyone answers the call, all they hear is silence. The calling party that called in on ZAP/5 still hears the line ringing. It is very odd. We're using Asterisk 1.2.12.1, Zaptel 1.2.12, and Wanpipe 3.2.1 on CentOS 4.4. Thank you for your help!!! Tim Nelson Systems/Network Support Rockbochs Inc.
