I have had a similar problem (albeit with raw dialplans). First, Unlimitel
require your Asterisk box to talk SIP, and to live at a fixed IP. Tell
them that you nede to set outgoing callerid info.
You can then mangle the callerid anyway that you want. Not sure about
Trixbox, but the effect that you want in your extensions.conf is:
dial(sip/local-voip-phone&sip/[EMAIL PROTECTED],,o)
The 'o' flag tells dial() to pass the originating callerid info to the
outbound call.
I also have problems with tromboning (hairpinning) calls out to Rogers via
Unlimitel. At a minimum you need to disable SIP reinvites. Straight
outbound calls work OK, but tromboning is erratic (but only to Rogers).
