Re: [Siproxd-users] Configuration help needed for Cisco 7905

[Thomas R. <tr...@gm...>]

Hmm, the dumps look funny.

Your internal address 192.168.15.200 (which supposedly ist the internal IP of
the siproxd host) does unexpectedly show up in VIA header of incoming SIP
messages (whereas the matching outgoing message clearly did *NOT* contain the
internal IP but the public IP address).

This makes me believe *strongly* that some other toys in your network are
messing around with the SIP protocol. Do you have a SIP aware NAT
Router/Firewall in place (between siporxd and the Internet)? If so, do disable
*all* SIP processing on those devices. Siproxd will not work properly if some
other network device does fiddle around with SIP messages and rewrites IP
addresses.

I suspect that something does introduce the internal 192.168.15.200 IP address
upon receiving messages from the external SIP REGISTRAR, this the causes a
non-match within siproxd. See the incoming INVITE request, it is deirected to
"INVITE sip:cisco@192.168.15.200:5060 SIP/2.0" and not to the public IP as
expected. Siproxd is unable to find the correct internal SIP device for this
incoming call (as the mapping is based on the public IP address), leading to
the following log entry:

09:40:15 proxy.c:242 request [INVITE] from/to unregistered UA (RQ:
0000123456@85.234.150.85 -> cisco@192.168.15.200)

and a 408 Timeout being sent back to the requestor.


I hope this helps to further track down things.

Best regards,
/Thomas
