My aim is to set up a local SIP server so two android phones connected (via wifi) to this server can interact and call each other using SIP (imsDroid).
I've been messing with asterisk's server configuration during 4 days, with no luck. Followed hundreds of tutorials to configure asterisk (including official asterisk's quickstart) - always failed. I can't even connect to it using Zoiper on the same computer the server is running...
Asterisk seems too complicated to configure for my "simple" goal, so my question is:
What is the most easy-to-configure local sip server ?
Thanks !
