[Asterisk-Users] Cisco router and "488 Not acceptable here" messages
Are there any known problems with Cisco routers (Cisco 837) and SIP sessions? I have been trying to track down a problem for about 3 hours now and I think the Cisco router is the culprit!!! I keep getting "488 Not acceptable here" messages, which are apparently normally the message you get when a common codec can't be found. I'm also getting "chan_sip.c:3434 process_sdp: Insufficient information for SDP (m = '', c = '')" messages, which is strange because the m and c attributes are definitely there. When I looked closer, they are received on the first INVITE, then asterisk says 'proxy auth required', but the INVITE packet with the proxy auth doesn't have the attributes. A tcpdump on the asterisk server confirms this. But, when I do a ethereal dump on my PC where I'm running SJphone, the attributes are there in the packet. So something is futzing with my packets, and screwing them up. There is a Cisco router on my end of the link, so I'm suspecting that! Any suggestions? Thanks James

Additionally, just to satisfy myself that I wasn't going mad I changed the port from 5060 to 5070 and now things are working, so something is definitely playing up on port 5060.
