I am sure this has been asked before, but I couldn't find it.

I am using avant fax with t38modem with about 10 channels on a sip trunk to a pbx.

My question: is it possible to specify the outbound caller ID of the fax to that of the fax number that is on the user account of the user who put the fax into the queue.

Thanks in advance.
