Feature Requests

there is the feature of sip proxy in monowall but the problem is from where i belong, sip protocol is bloced so as to use voip phones, i need to install this small software in my pc behind monowall that actually takes sip packets from the ip phone etc and encapsulated them in a normal UDP packet and then sends it over to the server, now the problem is if the pc running that software doesnt have the WAN ip then the DID feature for incomming calls cant work as the software needs to listen directly on the wanip then only can it receive calls so the sip proxy needs to be modified to work with such vpn enabled voip.
if any one interested then i can send them that small software as well as provide a sample pin for testing purposes
