[Serusers] Asterisk + OpenSER integration successful

[satish patel]

Dear ser guys..
 
 
                    I have done asterisk with openser integration after spending 2 and 3 days...not time to get nice cold beer... 
 
 I am user openser front of Asterisk. All sip client register on OpenSER server  and call to local extension without Asterisk. caz Asterisk is a media server which are useing only for PSTN calling. When any sip client dialing outside number means mobile number or any outside number Openser forward call to Asterisk and asterisk forward it on PSTN use the E1 or FXO line. ( In my case it is E1 ). 
 
 OpenSER only user for SIP users or SIP proxy server it can only handle sip request.
 
 Asterisk is Media server which can handle IVR , confrance , VoiceMail, and Meetmee or PSTN application. when call come down from PSTN Asterisk forward it on OpenSER as per dialplan configuration.
 
 It can handle 1000 of call and you can use it on large production.
