We first went that route, but found that it's not efficient.  Our inbound volume is low, so running through a script to find the user at a paricular device was easy enough.  

Outbound dialing proved to be a bit tougher.  Since access to specific services and dialing patterns is done at the original sip load based on what context the device belongs to, the only way we could think of allowing restricted dialing after user login was to include a script that all devices use to check what user is logged on it and thus allow/disallow that dialing pattern.

Our current outbound volume is 2 calls/second.  We expect that to hit 4 calls/second.  Running a script to check permission sets based on what user is logged into a particular device 4 times per second does not seem to be a particular good use of cpu cycles.

Since it's possible to do without code modification, I understand there would be no interest/support for a modification similar to what we want to do.  Perhaps we need to dig further and pose it as a user question on the appropriate forum.  In the mean time we will just patch against new versions and run it unsupported.

Thank you for your comments and time.
