Hi all, I'm trying to register with a provider without success. I'm able to do it from my snom 300 phone as well as zoiper softphone. On the phones, all I did was set <fake substitute values below> account : username registrar : sip.provider.com outbound proxy : 8.8.8.8 and it sends the register to 8.8.8.8 with a register packet like so in http://pastebin.com/XME4UknQ in fs, i created a provider with values http://pastebin.com/Q6i6Njxu and it's not registering. the difference in the sip trace is that although the request is sent to network address 8.8.8.8 the "Request-URI Host Part" uses the values from my proxy setting instead of "sip.provider.com". Sip trace from fs here -> http://pastebin.com/Pfgsu28s (Please ignore the user agent, this was sent from fs. I was experimenting with the "user-agent-string" param). How can I setup fs so that it'll send to the outbound proxy address but the Request-Line still shows REGISTER sip:sip.provider.com SIP/2.0 Thanks, Mervyn
