Ok so I'm running OpenWRT  Backfire 10.03 as my firewall and I've got a couple of devices I'm trying to use as SIP softphone clients for my work and I can't get any inbound audio working. I know that the SIP clients work as in our office I'm able to connect to our SIP service without any issue.

I can make outbound calls, I just can't hear any inbound audio.

I've been through a variety of options such as
 * Enable Proxy
 * Enable STUN
 * Enable ICE

My thoughts now are what can I tweak on my firewall given that there isn't an issue with the Vanilla vendor firmware on a similar TP-Link device at work.

I don't think you should need anything tweaked on OpenWRT from default with regards to SIP, I've never had any issues with it myself.

I upgraded to Backfire not that long ago at home.

Must be an after effect of some of my own firewall rules then.

Might start with a fairly vanilla config and then start adding some rules back in.
