Hi, all. I am from Singapore, we deployed a few PABX based on Asterisk.
Here in Singapore there are two Teleco providing E1 pri service, we
encountered a strange problem : when calling a number that is
unavailible or line suspended, one of the E1 provider keep the call
ongoing, because there are system announcement like "The line currently
I have something similar on a european E1. I do think this has
something to do with the PBX.. (asterisk in this case)
I have the same 'issue' on a BRI (ISDN) interface. The 'old' PBX (a
classic PBX) did sent out the telco announcement.
I have tried changing priindication, but this didn't help. I can see
the hangup_cause and can play prompts according to the hangup_cause,
but I would prefer using the telco announcement.
Have you tried progressinband=yes? As far as understand it, it forwards
early RTP (that is, stuff that is received prior to the ANSWER), which
might just do the trick.
I had this working when interconnecting with Chile mobile. When somebody
is on the line, they have some music and a message in spanish! Needless
to say, with g729 the music part sounds pretty awful (in fact it already
sounds awful with g711 anyway...)
NB: As far as I can tell, progressinband=yes isn't supported in
chan_h323, which is a shame :(
Cheers,
Jean-Michel.
