[SR-Users] Asterisk Integration w Kamailio and Zoiper phone problems

Hi, I have a virtual environment setup and am trying to get the integration of Kamailio and Asterisk to a least be able to make a phone call based off the Asterisk Hello World example. I do the following: 1. I'm running Ubuntu 14.04 and Oracle Virtual Box 2. I Integrate Kamailio and Asterisk based off of the asipto kb: http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb with both of them running on the same VM. 3. I've modified sip.conf and extensions.conf to have entries that tie together phones 101 and 102 3. I start asterisk with "asterisk" and "asterisk -rvvvvvv" 4. I install and setup the Zoiper Softphone as indicated in the tutorial. https://wiki.asterisk.org/wiki/display/AST/Hello+World 5. In Zoiper I hardcode the Domain: xxx.xxx.xxx.xxx:5080 and also enter the username and password. 6. I'm doing all of this without access to an internet connection so that's why I hardcode the IP address. 7. After setting of the Zoiper softphone I try to get it to communicate with Asterisk, but I get a 408 request timeout. Any ideas as to what might be wrong? Thanks, Brian
