[Vtigercrm-developers] Asterisk Good News

yes, I completely understand that, I am just aiming for a bit more 
instant gratification on installing the module, I want it to be a case 
of installing the module, tell the module where your upstream PBX is and 
where your sip proxy is, and tell your handsets to use the proxy and it 
all starts working. The opensips dependency is a bit annoying really, if 
I could find a nice PHP SIP server library I would much rather have a 
self-contained system where the vtiger server itself acts as the SIP proxy.
