[Asterisk-Users] Weird Zaphfc - not dialling non-local numbers

[John McEleney]

Hi all,

I really hope that you guys can help, because I've been tearing my hair 
out for the past 5 hours on this one.

I have a Zaphfc (BRI) card in TE mode connected to the S-Bus of a Nortel 
Meridian phone system. Phone calls from the Nortel to say MSN 510 are 
correctly being sent to the right SIP phone. When asterisk dials say 
Zap/g2/224 (a Nortel internal extension) the call goes through, no problem.

The wierd bit is, when Asterisk calls Zap/g2/907748xxxxxx to reach an 
mobile on an outside line, the call connot be connected. I know for a 
fact that the '9' prefix is valid for use on the S-Bus, because I 
previously used AVM Fritz (CAPI) card on the same S-Bus.

If any can help, I will be eternally grateful.

Thanks,
John
