This is a strange one. I make a call using an FXO analog line (mod_openzap). During the call, I dial 200 and FS parks the call. This is a Sangoma card using wanpipe. Is there some kind of setting in there where it interprets DTMF? Is there a way to see what OpenZAP is writing "ending bridge by request from write function"? Thanks for any help on this! -Troy Here's where it happens (phone number is redacted). 2010-02-11 11:49:48.455727 [DEBUG] switch_rtp.c:2417 RTP RECV DTMF 2:1680 2010-02-11 11:49:48.466015 [DEBUG] zap_io.c:1870 1:1 GENERATE DTMF [2] 2010-02-11 11:49:48.895733 [DEBUG] switch_rtp.c:2417 RTP RECV DTMF 0:1280 2010-02-11 11:49:48.905726 [DEBUG] zap_io.c:1870 1:1 GENERATE DTMF [0] 2010-02-11 11:49:49.455734 [DEBUG] switch_rtp.c:2417 RTP RECV DTMF 0:1360 2010-02-11 11:49:49.465771 [DEBUG] zap_io.c:1870 1:1 GENERATE DTMF [0] 2010-02-11 11:49:49.706363 [DEBUG] switch_ivr_bridge.c:469 OpenZAP/1:1/602xxxxxxx ending bridge by request from write function 2010-02-11 11:49:49.706363 [DEBUG] switch_core_session.c:638 Send signal sofia/internal/105@10.0.1.202 [BREAK] 2010-02-11 11:49:49.706363 [DEBUG] switch_ivr_bridge.c:562 BRIDGE THREAD DONE [sofia/internal/105@10.0.1.202] 2010-02-11 11:49:49.706363 [DEBUG] switch_ivr_bridge.c:582 Send signal OpenZAP/1:1/602xxxxxxx [BREAK] 2010-02-11 11:49:49.716359 [DEBUG] switch_core_session.c:638 Send signal OpenZAP/1:1/602xxxxxxx [BREAK] 2010-02-11 11:49:49.716359 [DEBUG] switch_ivr_bridge.c:562 BRIDGE THREAD DONE [OpenZAP/1:1/602xxxxxxx] 2010-02-11 11:49:49.716359 [DEBUG] switch_ivr_bridge.c:582 Send signal sofia/internal/105@10.0.1.202 [BREAK] 2010-02-11 11:49:49.716359 [DEBUG] switch_ivr_bridge.c:640 (OpenZAP/1:1/602xxxxxxx) State Change CS_EXCHANGE_MEDIA -> CS_PARK 2010-02-11 11:49:49.716359 [DEBUG] switch_core_session.c:1018 Send signal OpenZAP/1:1/602xxxxxxx [BREAK] 2010-02-11 11:49:49.716359 [DEBUG] switch_core_state_machine.c:351 (OpenZAP/1:1/602xxxxxxx) State EXCHANGE_MEDIA going to sleep 2010-02-11 11:49:49.716359 [DEBUG] switch_core_state_machine.c:314 (OpenZAP/1:1/602xxxxxxx) Running State Change CS_PARK 2010-02-11 11:49:49.716359 [DEBUG] switch_core_state_machine.c:357 (OpenZAP/1:1/602xxxxxxx) State PARK 2010-02-11 11:49:49.716359 [DEBUG] switch_core_state_machine.c:206 OpenZAP/1:1/602xxxxxxx Standard PARK
