asterisk users - Feb 2007 - dialplan logic based on caller ID

Hello!

Is there any easy way to use the caller ID "display info" 
(CALLERID(name) in Asterisk) in dialplan just as we could use the number in:

exten => _X./67803287, 1, <action>

I have a SIP GSM device, and when a call comes in, it passes me the 
caller ID like so:

-- Sip message Header:
From: "67803287" <sip:gsm@192.168.10.1>;tag=...

-- Asterisk variables:
CALLERID(num) = gsm
CALLERID(name) = 67803287


I would like to make a logic based on the caller id, that would also 
work in the case of zap devices that set variables like:
CALLERID(num) = 67803287
CALLERID(name) = ""

Anyone has a clue (without having to complicate things too much)?

Thank you,
Fran?ois.

Are there any scripts out there that would help me stress test two boxes
that are setup back to back with 4 PRI connections?  We're having
problems with Sangoma cards w/ PCI-e on HP DL385 G2 hardware and I'm
tired of "testing" them in a production environment.  As Sangoma
provides firmware updates (and various other shots in the dark) I'd like
to be able see if the problem is fixed in an isolated environment.  I
just need a way to simulate call volume on 4 t1s.
