I have a customer who ported all their numbers over to a PRI, so the faxes had to go on to an analog extension in the system. DID calls into the system work fine, but outgoing faxes (and calls with by butt set) get a busy signal upon going off hook. As a workaround, I have outgoing calls going out on the still active Loop start lines. What am I missing? Also, I have automatic trunk seizure enabled for these extensions.
