Asterisk Integration - Multiple PBX's

[socain]

We have several users across different PBX's. Can the config be changed to allow for multiple PBX's? If not, how much development would it take to make the option configurable at the users settings level (i.e Have the server IP setting just like the context setting in the users zimlet options)? If it worked in this fashion then this zimlet would work perfectly for us.

Thanks!
