[Asterisk-Users] callerid= being ignored

[BK [address only for mailing lists]]

Hi

I have defined my SIP phones like this ...

[Sip1]
username=gs1
callerid= "Full name" <1001>

etc etc

Now, when I do this in a given extension

exten => nnnn,1,NoOp(${CALLERIDNUM})

then I get "<gs1>" as callerid and not "<1001>" as defined with callerid=

Sure, I could set the usernames to their respective extensions, but I 
don't want to do that. I'd like to keep login names independent of 
extensions.

Is there any fix for this so that the real callerid shows up?

thanks in advance
regards
