Product: Adtran 924eG3 w/LFXO
Firmware: ADTRAN, Inc. OS version R12.2.0.SA.E
Running into an issue where the phones behind the Transparent SIP Proxy are refusing to register correctly. If the phone is connected behind another Vendor's router/firewall they work fine. The phones are registering to a metaswitch installation.
Seeing this in the logs:
12:42:34.517 SIP.PROXY ROUTING Modify response for proxy
12:42:34.517 SIP.PROXY ROUTING ERROR! Failed to set local address.
12:42:34.517 SIP.PROXY ROUTING ERROR! proxyResponseAsServer failed.
12:42:34.518 SIP.PROXY ROUTING ERROR! proxyResponse failed.
I can ping the SBC from the Adtran unit and can set up the FXS ports to register without issue.
I have several of these out in the field with a very similar config that are working fine.
Extremely puzzled as to why this one isn't working.
Attached is a sanitized copy of the configuration and logs.
Any ideas?
