Hello,
I am making good steady progress with a msc to sip service using libss7, but
on testing sip inward to msc calls it appears that the leading zero is
missing from both the called number and the calling number, which causes
both routing issues in the msc and the caller id showing up on the called
mobile missing the leading 0 for caller id, I suspect it's configurable in
the zapta.conf file but googling has not yet helped?
The call is dialled as "exten => _07892111XXX,1,Dial(Zap/37/${EXTEN})"
And the 2nd question is how to dial from Chan 37 and up, instead of
hardcoding it as Zap/37?
One further question puzzling me is how might be possible to play music
instead of ringback as do other cell operators? Can asterisk do this?
Regards
Magnus
