I have an ATCOM ATA that is trying to connect to an asterisk server using IAX. The ATA and Asterisk are on the same subnet, not firewall/nat etc. Below is a a log excerpt, showing the REGREQ received, and then Asterisk goes on to send lots of REGAUTH...and this continues for a while, but the ATA is never registered (iax2 show peers shows not registered). Any help would be appreciated. It sure LOOKS like a lot of TX for very few RX frames...so my first guess was network related but I'm not making any progress with that theory Thanks Tx-Frame Retry[001] -- OSeqno: 003 ISeqno: 001 Type: IAX Subclass: PING Timestamp: 21003ms SCall: 10027 DCall: 18442 [192.168.67.20:4569] Tx-Frame Retry[001] -- OSeqno: 003 ISeqno: 001 Type: IAX Subclass: PING Timestamp: 21006ms SCall: 14940 DCall: 18442 [192.168.67.20:4569] Rx-Frame Retry[Yes] -- OSeqno: 000 ISeqno: 000 Type: IAX Subclass: REGREQ Timestamp: 00003ms SCall: 18443 DCall: 00000 [192.168.67.20:4569] USERNAME : ALARM-ATA REFRESH : 60 Tx-Frame Retry[003] -- OSeqno: 000 ISeqno: 001 Type: IAX Subclass: REGAUTH Timestamp: 00014ms SCall: 02267 DCall: 18443 [192.168.67.20:4569] AUTHMETHODS : 2 CHALLENGE : 121149566 USERNAME : ALARM-ATA Tx-Frame Retry[002] -- OSeqno: 001 ISeqno: 001 Type: IAX Subclass: LAGRQ Timestamp: 10013ms SCall: 02267 DCall: 18443 [192.168.67.20:4569] Tx-Frame Retry[001] -- OSeqno: 002 ISeqno: 001 Type: IAX Subclass: LAGRQ Timestamp: 20013ms SCall: 02267 DCall: 18443 [192.168.67.20:4569] Tx-Frame Retry[000] -- OSeqno: 003 ISeqno: 001 Type: IAX Subclass: PING Timestamp: 21016ms SCall: 10572 DCall: 18443 [192.168.67.20:4569] Tx-Frame Retry[002] -- OSeqno: 000 ISeqno: 001 Type: IAX Subclass: REGAUTH Timestamp: 00015ms SCall: 14112 DCall: 18443 [192.168.67.20:4569] AUTHMETHODS : 2 CHALLENGE : 530555480 USERNAME : ALARM-ATA Tx-Frame Retry[001] -- OSeqno: 003 ISeqno: 001 Type: IAX Subclass: PING Timestamp: 21015ms SCall: 12659 DCall: 18443 [192.168.67.20:4569] Tx-Frame Retry[001] -- OSeqno: 001 ISeqno: 001 Type: IAX Subclass: LAGRQ Timestamp: 10014ms SCall: 14112 DCall: 18443 [192.168.67.20:4569] Tx-Frame Retry[000] -- OSeqno: 002 ISeqno: 001 Type: IAX Subclass: LAGRQ Timestamp: 20016ms SCall: 00480 DCall: 18443 [192.168.67.20:4569] Tx-Frame Retry[000] -- OSeqno: 000 ISeqno: 001 Type: IAX Subclass: REGAUTH Timestamp: 00002ms SCall: 05489 DCall: 18443 [192.168.67.20:4569] AUTHMETHODS : 2 CHALLENGE : 399007934 USERNAME : ALARM-ATA -------------- next part -------------- An HTML attachment was scrubbed...
