Hi,
We're running sipXecs 4.0.4 on CentOS 5.2 on a machine, which has 2
network cards eth0 and eth1.
The eth0 is supposed to be in the internal network and this is where the
sipXecs is bound to. The "Server IP address" is set to eth0's IP address
and there's no reference of eth1's IP address anywhere in the
/etc/sipxpbx, nor in the config backup archive.
The eth1 is the "public" interface through which one can access the
machine from "outside".
We've observed, that when making softphone to PSTN calls, the sipxbridge
throws the outgoing invite back with "403 Request not issued from SIPX
proxy server". Analyzing the SIP traces we found, that the VIA headers
sometimes have the IP address of eth1. Checking the sipxbridge source it
looks like the 403 must do with the VIA headers having the eth1 IP
address.
The SIP messages are all UDP -apart from sipxproxy->sipxbridge- and the
DNS running on the machine resolves the hostname to the eth0 IP address.
Has anyone seen this before?
Thanks,
Chris
