Hi Can anyone help with my following problem connecting asterisk to a new provisioned isdn30e line. At long last I have had BT install our new isdn 30 (I421) line for our asterisk server after 3 months of waiting. Before this we have used asterisk with a tdm400 and some analogue lines. I have installed a digium TDM 205 e1 card with port 1 connected to the isdn30 box via a rj45 network lead. (wired like a normal patch lead NOT crossover). Is this correct ?. I have no red warning lights just green ok lights. Asterisk,libpri and zaptel are the latest ones from asterisk.org. On trying to dial using the isdn30 im getting the following error Circuit/Channel congestion -- Executing Set("SIP/602-9989", "GROUP(901392275533)=OUTBOUND_GROUP") in new stack -- Executing GotoIf("SIP/602-9989", "0?5") in new stack -- Executing Set("SIP/602-9989", "GROUP(602)=OUTBOUND_GROUP") in new stack -- Executing Dial("SIP/602-9989", "zap/g1/14101392275533") in new stack Aug 23 16:26:43 NOTICE[6823]: app_dial.c:1040 dial_exec_full: Unable to create channel of type 'zap' (cause 34 - Circuit/channel congestion) == Everyone is busy/congested at this time (1:0/1/0) == Auto fallthrough, channel 'SIP/602-9989' status is 'CONGESTION' ztcfg -vvvv shows PAN 1: CCS/HDB3 Build-out: 133-266 feet (DSX-1) SPAN 2: ESF/B8ZS Build-out: 0 db (CSU)/0-133 feet (DSX-1) Channel map: Channel 01: Clear channel (Default) (Slaves: 01) Channel 02: Clear channel (Default) (Slaves: 02) Channel 03: Clear channel (Default) (Slaves: 03) Channel 04: Clear channel (Default) (Slaves: 04) Channel 05: Clear channel (Default) (Slaves: 05) Channel 06: Clear channel (Default) (Slaves: 06) Channel 07: Clear channel (Default) (Slaves: 07) Channel 08: Clear channel (Default) (Slaves: 0 Channel 09: Clear channel (Default) (Slaves: 09) Channel 10: Clear channel (Default) (Slaves: 10) Channel 11: Clear channel (Default) (Slaves: 11) Channel 12: Clear channel (Default) (Slaves: 12) Channel 13: Clear channel (Default) (Slaves: 13) Channel 14: Clear channel (Default) (Slaves: 14) Channel 15: Clear channel (Default) (Slaves: 15) Channel 16: D-channel (Default) (Slaves: 16) Channel 17: Clear channel (Default) (Slaves: 17) Channel 18: Clear channel (Default) (Slaves: 1 Channel 19: Clear channel (Default) (Slaves: 19) Channel 20: Clear channel (Default) (Slaves: 20) Channel 21: Clear channel (Default) (Slaves: 21) Channel 22: Clear channel (Default) (Slaves: 22) Channel 23: Clear channel (Default) (Slaves: 23) Channel 24: Clear channel (Default) (Slaves: 24) Channel 25: Clear channel (Default) (Slaves: 25) Channel 26: Clear channel (Default) (Slaves: 26) Channel 27: Clear channel (Default) (Slaves: 27) Channel 28: Clear channel (Default) (Slaves: 2 Channel 29: Clear channel (Default) (Slaves: 29) Channel 30: Clear channel (Default) (Slaves: 30) Channel 31: Clear channel (Default) (Slaves: 31) but this does show in the /var/log/messages Aug 23 16:32:21 WARNING[6778]: chan_zap.c:6347 handle_init_event: Detected alarm on channel 28: Recovering Aug 23 16:32:21 WARNING[6778]: chan_zap.c:1435 zt_disable_ec: Unable to disable echo cancellation on channel 28 FOR each channel and then Aug 23 16:32:26 NOTICE[6778]: chan_zap.c:6340 handle_init_event: Alarm cleared on channel 28 FOR each channel Can anyone help as have I missed somthing simple.
