I had something very similar happen a few months ago with SIP. I was using
analog phone <-> Grandstream HT-286 #1 <-> Linksys router <-> Internet <-> Tik Router <-> Local network with Asterisk server and internal HT-286s. I ran torch when trying to get adapter #1 to connect to the Asterisk server. The request came into the * server just fine, the reponse for some reason was trying to leave the internal Tik router network with the internal IP of the #1 adapter. That just does not work. Luckily there was a place to add a STUN server. http://www.freeworlddialup.com/ has a public STUN server you can use. It helped adapter #1 figure out what kind of firewall it was behind along with the public IP of the above Linksys router.
