[OpenSIPS-Users] Some Guidance

[Douglas Lane]

Hi Richard,

Big thanks for the assistance, I've managed to build a nice route script 
to handle pulling the CLID ranges out of the dialplan, and checking if 
the from display name or P-Asserted-Identity contain a number within the 
range.

Thanks once again

Thanks
Doug
