Subject: [Asterisk-Users] Asterisk / 183 message
Hello,
My company is doing some * testing with our Class 5 softswitch and had 
some questions regarding ringback being provided to our PSTN users (off 
--> on net calling)
Currently with MGCP subscribers, we know the PSTN ringing is provided by 
a digital PBX for example,    However, it looks like with SIP, our 
softswitch is relying on MGCP signaling on our PSTN gateways to provide 
ringback to the PSTN network - this makes complete sense (gateway to 
PSTN gets a S: rg).
The problem is that some of our older gateways don't support MGCP event 
signaling, so I was trying to get Asterisk to send all SIP calls to our 
switch with a "183" message so maybe our switch will cut the call 
through two-way immediately.  Currently Asterisk is sending 180/ringing 
messages to our switch. 
Is there a way to have Asterisk send 183 messages to my peer defined in 
sip.conf ?
Thanks,
Dave
