[Asterisk-Users] tdm04b outbound call question

[Rich Adamson]

Have a newly installed * box (RH ES3, current cvs head) with a tdm04b
(4-port fxo) connected to four US CO Centrex lines. Inbound calls are
being handled correctly via entries shown below. However, outbound
4-digit calling (eg, sip phone dials 8125 or iax2 call dials 8125)
always receives a CO Centrex message "...cannot call this number,
contact your operator...". I'm 50 miles away from this system and am
trying to debug this remotely. An ordinary analog phone plugged into 
the same zap/1 pstn line _can_ dial 8125 and have that centrex 
extension rings.

The cli shows:
    -- Executing Dial("SIP/6101-0553", "Zap/1/8125") in new stack
    -- Called 1/8125
    -- Zap/1-1 answered SIP/6101-0553
    -- Hungup 'Zap/1-1'

Any thoughts on what might be happening here, or how to diagnose the
issue?
