I am attempting to forward a legacy DID to an external Number. We have a block of DIDs 212-555-8300 through 212-555-8399. Specifically 212-555-8302 is a FAX Machine connected to an ONS card. The office has a new fax on a POTS line 212-555-8901. The pots line is not connected to the PBX in any way. The users would like to remove the their old fax machine to free up some space used by 8302.
I created a System speed call number #8302, that dials 95558901 (new pots). Type is INt, Toll-override enabled. It works, I can dial from any extension, #8302 and it rings the new Fax machine.
I created a Call Rerouting Always Alternative assignment 99. I changed the Originating Device DID, Originating Device TIE, Originating Device CO, Originating Device INT from No Reroute to Reroute; and gave it the Directory Number of #8302.
I changed the Call Rerouting Assignment for Number 8302, Call Rerouting Day,Call Rerouting Night 1, Call Rerouting Night 2 from 1 to 99. Now if anyone calls extension 8302 internally it rings the new Fax Machine 8901. If I call from my Cell phone or another POTS line it indeed rings the new Machine 8901 as well.
The problem: I reached out to my 5 other offices to send test faxes to the Legacy Number 212-555-8302. (2) of them made it through to the new fax machine, and (2) reported that the number rang indefinitely, the other said their fax machine read PAUSED. Is there something I missed? Anything that has to do with 1st, 2nd Alternative routes? Do I have to compensate for a busy signal?
