Hi, I signed up with flowroute and was trying to setup an external gateway to use the test credits. I do manage to register using just a softphone without FS in the picture. I followed the provider example in the wiki. I have been given only the following SIP credentials from flowroute: SIP Registrar/Proxy username and auth-username: its the same value for both password I have iptables stopped and selinux disabled. I don't think its a NAT issue as I have an incoming DID from ipkall working perfectly fine. It's a 99% default config. I made no changes to either vars.xml or /conf/sip_profiles/external.xml Here is my /conf/sip_profiles/external/freeswitch.conf.xml http://pastebin.freeswitch.org/13426 SIP trace: http://pastebin.freeswitch.org/13427 Thanks gsin
