[Asterisk-Users] No Media for Ringing Indication

[Miroslav Nachev]

   Hi,

   When we use mISDN and Asterisk some times after Dial the PSTN
doesn't send Ringing Media. The indication is coming and is displayed
on Asterisk CLI but there is not sound. This is very unpleasant for
the user which can't see the Asterisk CLI to know that the call is in
Rining State.
   How can catch Ringing Event that is coming from ISDN channels and
then to play rining media in case that PSTN is not sending such media.
The same question for the other states like busy, etc.

   Any help or suggestions?


   Best Regards,
   Miroslav Nachev
