[Asterisk-Users] SIP => PSTN Pri Causes

[markus monka]

hi,

we use ser for signalling and asterisk as gateway.
is there a possibility to configure the pri-causes
for SIP Responses.

SER => 404 NOT FOUND => PSTN .. 

At this moment the Caller gets 

"no connection under this number"

It would be nice to signalling something like:

"participant not available at present"

Asterisk CVS-HEAD-07/07/04-18:53:32 ,same time we 
checked out libpri.

Any ideas? 

thx,
Markus
