Linux routing of SIP protocol
Posted on 2013-01-28
Need some assistance with creating a LAN proxy for routing SIP traffic out on a specific WAN.
Is is possible to creating a route on a Linux box to do this, or indeed use something like Squid?
I have tried a few iptables commands but to no avail.
So, in the end, need the following
SIP client > port 5060 > Linux box > sipserverabc.com:5060
Don't know if SIP protocol supports this type of routing or whether is suffers from problems like FTP where it uses multiple ports.
