[asterisk-users] progress problems from SIP to PRI

[Klaus Darilion]

Hi!

I have problems when bridging from SIP to PRI. As soon as the setup 
message is sent, Asterisk replies with 183 to the sender.

Although there is nor PROGRESS message received, the 183 is sent as the 
SIP channel received a voice frame and thus activates early media.

I wonder why Asterisk reads from the PRI although there was no PROGRESS 
message received yet.

I want to get rid of this 183 - it should be sent only when a PROGRESS 
is received on the PRI.

Can this be configured somehow?

thanks
