Digital DID Trunking to Overflow Analog DID Trunking

[NTI620]

I keep seeing this programmed at various sites, and I am under the belief that this is not possible. Does anyone know if the CO can automatically implement this for digital DID to analog DID.

YOU WOULD HAVE TO ASK YOUR LOCAL LEC, HAS NOTHING TO DO WITH SWITCH

This is an issue to the PBX world because I am sure that there are other PBX's that have this configuration. Of course it has to do with LEC CO, if you'd bothered to read the question you would know that.

NTI620,

Are you asking the following question??

When I get more than 23 (or 24) inbound DID calls through my PRI (T1) at the same time, can the extra calls rollover to an analog DID circuit or set of circuits and reach my switch through an analog DID trunk instead of the PRI (t1)???

If this is the question, then I have been repeatedly told NO by Verizon. This would be an extremely useful feature in the event of a PRI (t1) Failure which I have had on several occasions without any means of receiving incoming calls.

Actuallly, if the telco could provide this service, it would require almost no programming at the PBX because all lines could be treated as inbound DID and the switch would not really care whether it came in on a digital or analog trunk, cause the routing would be the same.

If you do know of such an arrangement, please post the details so I can get Verizon to give me a similar circuit.

I agree that it would be useful, but I have also been told that the answer is no. Thanks for restoring my belief that the users of this service do read the questions before answering them.

By the way, I totally read the question. I just don't have a clue as to the answer.

This may not solve the problem but it might help salo0920. I to have Verizon and as a disaster recovery plan I have certain DID numbers that are ported to ride analog trunk numbers if my T1 goes down. I just make a call into Verizon and within 5 to 10 minutes I have at least my main numbers functional.

You could use a 2nd PRA with same d-channel, that way they both use the same ddi ranges. Only problem is, if the 1st PRA with the d-channel fails then 2nd PRA is also down

Hawks,

Do you know what this service from Verizon was called? They were touting a "Custom Call Redirect" feature like that which you described, but there was a large one time setup fee and then a monthly fee for all lines you wanted in the redirect programming. It just didnt seem right to pay Verizon every month for a service that would be used only if their lines got trashed.

I wish I could charge my customers for a service and then charge them some more in case it didnt work!

I agree, I'll see if I can find out it's been so long ago and luckily I have not had to use it.

Well, my scenery is completely different. I have several E1 DID in CAS MFCR2. I got them programmed with an Alternate route to 9800 in case of congestion and failure.

Those PTCs have Alcatel R12 and Ericsson AXE. One of them only does the reroute manually, it has Siemens ESWD.
In a small city, the PTC has an old Plessyus CO and they couldn't offer that service.

I have 4 European PRIs with alternate route to a local phone number provided by other PTC.
