Is there a better way to route calls to different campaigns

[Eugene]

Hello!

I'd like to ask for an advice about a way to route inbound calls to different campaigns based on request to CRM.

Currently I use the following procedure:

-- Incoming call goes to default (internal) extension.
-- The extension invokes AGI script.
-- AGI script polls CRM and sets proper next extension for the call

Mentioned 'next extension' is actually DID associated with proper ingroup and campaign.

Could the task be accomplished in a better/cleaner/different way?

Thank you!
