[Asterisk-Users] Some problems setting outgoing PRI Origination Number

[Paul Belanger]

Hello,

Quick Diagram:

Telco-PRI -> Asterisk <- Norstar PRI -> Norstar PBX
   (DMS100)  (TE405P)     (DMS100)
                |
                |
                V
           Cisco 7960G
              (SIP)

I'm trying to change the Origination Number on my outgoing PRI, and running into a weird
problem.  If I make a call from a SIP extension off asterisk using the following context:

[from-sip]
exten => 800,1,Answer
exten => 800,2,SetCallerID(6132718xxxx)
exten => 800,3,Dial(Dial(${TRUNK-TELCO}/5551234)

I am able to change the Origination Number!

However if I call from behind the channel bank, I am unable to change the number.

Any ideas why I can set it using SIP extension only?
