Hi,
I have the following setup:
(sip clients) -internet- asterisk A -IAX- asterisk B -PRI- (pstn)
This works fine for regular calls sip->pstn. the calls go through
perfectly. However, when one of the sip clients (a snom320) is set to
redirect to the pstn, then all I hear is congestion tones when I call that
sip client. I am at a loss to see why the redirected call would fail, when
the redirecting sip client can dial the same number successfully.
In the pri debug trace below (from asterisk host B), the sip phone at
extension 340340 (local ext) is set to redirect to 131166 (a pstn number).
I notice that "340340" appears in the PRI debug on asterisk host B
even
though it has no direct contact with the sip client. The callerid is set
exactly the same as a regular call from ext 340340 would be. What else is
different from asterisk host B's point of view in this case?

Can anyone suggest what might be causing this behaviour?
