[OpenSBC] OpenSBC Gives 420 Bad Extension on SIP Subscribe
|

I have OpenSBC 1.15 RC3 running in B2BUA Upper Reg Mode, sitting in front of a sipXecs deployment. User registrations and calls are being successfully routed through OpenSBC -- but I'm having a problem with SUBSCRIBE events. I'm using X-Lite as my UA, and when X-Lite sends a SUBSCRIBE to OpenSBC (to gather contact presence information), OpenSBC sends a "420 Bad Extension" response. I've also seen the same behavior when I've used Sip Communicator. Are there any settings in OpenSBC that could affect its ability to respond to Sip SUBSCRIBE requests? I've included log entries below to demonstrate the issue: 2009/01/21 09:00:55.997 INF: CID=0x0e8d <<< SUBSCRIBE sip:us...@si...main SIP/2.0 SRC: 10.0.0.1:46288:UDP enc=0 bytes=673 2009/01/21 09:00:55.997 DBG: CID=0x0e8d 2009/01/21 09:00:55.997 DBG: CID=0x0e8d SUBSCRIBE sip:us...@si...main SIP/2.0 2009/01/21 09:00:55.997 DBG: CID=0x0e8d From: "usera" <sip:us...@si...main>;tag=f449fc5d 2009/01/21 09:00:55.997 DBG: CID=0x0e8d To: "User B" <sip:us...@si...main> 2009/01/21 09:00:55.997 DBG: CID=0x0e8d Via: SIP/2.0/UDP 10.0.0.1:46288;branch=z9hG4bK-d8754z-5f50db05221c3b30-1---d8754z- 2009/01/21 09:00:55.997 DBG: CID=0x0e8d CSeq: 1 SUBSCRIBE 2009/01/21 09:00:55.997 DBG: CID=0x0e8d Call-ID: YTRkMjc1NGUyNjg5MTBlNDk2ZDQ4OTUwYzU4NmQxZTU. 2009/01/21 09:00:55.997 DBG: CID=0x0e8d Contact: <sip:usera@10.0.0.1:46288> 2009/01/21 09:00:55.997 DBG: CID=0x0e8d Event: presence 2009/01/21 09:00:55.997 DBG: CID=0x0e8d Subject: 2009/01/21 09:00:55.997 DBG: CID=0x0e8d User-Agent: X-Lite release 1100l stamp 47546 2009/01/21 09:00:55.997 DBG: CID=0x0e8d Expires: 300 2009/01/21 09:00:55.997 DBG: CID=0x0e8d Max-Forwards: 70 2009/01/21 09:00:55.997 DBG: CID=0x0e8d Accept: multipart/related, application/rlmi+xml, application/pidf+xml 2009/01/21 09:00:55.997 DBG: CID=0x0e8d Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, NOTIFY, MESSAGE, SUBSCRIBE, INFO 2009/01/21 09:00:55.997 DBG: CID=0x0e8d Content-Length: 0 2009/01/21 09:00:55.997 DBG: CID=0x0e8d 2009/01/21 09:00:55.997 DBG: CID=0x0e8d 2009/01/21 09:00:55.998 DTL: CID=0x0e8d NIST(4156922636) *** CREATED *** - NIST|YTRkMjc1NGUyNjg5MTBlNDk2ZDQ4OTUwYzU4NmQxZTU.|z9hG4bK-d8754z-5f50db 05221c3b30-1---d8754z-|SUBSCRIBE 2009/01/21 09:00:55.998 DTL: CID=0x0e8d NIST(4156922636) Event(SIPMessage) - SUBSCRIBE sip:us...@si...main SIP/2.0 2009/01/21 09:00:55.998 DBG: CID=0x0e8d TRANSACTION: (NIST) SUBSCRIBE sip:us...@si...main SIP/2.0 State: 0 2009/01/21 09:00:55.998 DTL: CID=0x0e8d NIST(4156922636) StateIdle->StateTrying 2009/01/21 09:00:55.998 DTL: CID=0x0e8d NIST(4156922636) Event(SIPMessage) - SIP/2.0 420 Bad Extension 2009/01/21 09:00:55.998 DBG: CID=0x0e8d TRANSACTION: (NIST) SIP/2.0 420 Bad Extension State: 1 2009/01/21 09:00:55.999 DTL: CID=0x0e8d NIST(4156922636)HandleStateTrying->StateCompleted 2009/01/21 09:00:55.999 INF: CID=0x0e8d >>> SIP/2.0 420 Bad Extension DST: 10.0.0.1:46288:UDP SRC=10.0.0.20:5061 enc=0 bytes=436 2009/01/21 09:00:55.999 DBG: CID=0x0e8d 2009/01/21 09:00:55.999 DBG: CID=0x0e8d SIP/2.0 420 Bad Extension 2009/01/21 09:00:55.999 DBG: CID=0x0e8d From: "usera" <sip:us...@si...main>;tag=f449fc5d 2009/01/21 09:00:55.999 DBG: CID=0x0e8d To: "User B" <sip:us...@si...main>;tag=ce21c5bc4ae6dd1196cdcd16fb6551b7 2009/01/21 09:00:55.999 DBG: CID=0x0e8d Via: SIP/2.0/UDP 10.0.0.1:46288;branch=z9hG4bK-d8754z-5f50db05221c3b30-1---d8754z-;rport=46288;recei ved=10.0.0.1 2009/01/21 09:00:55.999 DBG: CID=0x0e8d CSeq: 1 SUBSCRIBE 2009/01/21 09:00:55.999 DBG: CID=0x0e8d Call-ID: YTRkMjc1NGUyNjg5MTBlNDk2ZDQ4OTUwYzU4NmQxZTU. 2009/01/21 09:00:55.999 DBG: CID=0x0e8d Server: OpenSBC v1.1.5-42 2009/01/21 09:00:55.999 DBG: CID=0x0e8d Content-Length: 0 2009/01/21 09:00:55.999 DBG: CID=0x0e8d 2009/01/21 09:00:55.999 DBG: CID=0x0e8d |
