[Asterisk-Users] Outbound Caller ID number on E1

[Garth van Sittert]

Thanks Steve

We replaced an old Siemens that used to produce the outgoing numbers 
correctly, so we must have the 3rd option.
The extensions are all set up to be in that range to provide DID.  When 
the SIP extensions dial out will they provide the extension number which 
gets prefixed with what?  Do I need to send the complete number, 3 digit 
area code + 4 digit extension to the Telko?  Does the zapata.conf add 
the prefix?  How can I check what callerid number is being passed to the 
Telko?
