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.
I have the same COS and trunk group as the digital sets. Here's another funny part. If I direct select a channel on the PRI using #9xxx with x being a channel number, I can only dial 3 digits before the channel goes busy. Weird. The only thing I can think of off the top of my head is that the software is 6.03 and not the latest, which was 7.3x I believe. Looking at some old release notes, there were issues corrected in regards to PRIs although they don't address this in particular. All this is a moot point anyway as the customer never wanted the fax numbers ported to the PRI to begin with and will be coming off the Aspire asap.
