Analog DID trunk dilemma

[pmcook]

I have a situation where I have a system waiting for installation. It is configured with 8 analog trunks and a full PRI. The idea was to install it using existing analog trunks then convert to PRI after they bring the fiber into the building. Well, turns out the site has analog DID trunks. Somewhat of an unusual sight these days. What can I do here? I am kicking around the idea of using their existing Definity system to route the calls the the IPO. I'm curious how everyone here might approach an interim solution. Otherwise I have to eat the loss and sit on this system for 8-10 weeks.

I would use the Definity as intermediate untill the PRI becomes active and the analog trunks are migrated.
Problem is that you will not have DDI for the time being unless you can setup IP trunk between them or a extra PRI on the Difinity.

I would also use Definity as a tandem switch - you can either use IP trunk OR a T1/QSIG trunk between IPO and Definity to deliver calls. Either will provide adequate call information to use IPO ICR tables. I've done this successfully in the past - a bit of a pain to set up, but it'll work indefinitely.

Just to be complete.
Incomming calls via a H.323 trunk with Qsig or a PRI/T1 Qsig trunk does not route through ICR, instead use the line shortcode to route the calls.
A shortcode like SC=XXXX TN=N Action = DialExtension LineID = 0 should be enough.

That's the plan, T1 between the two. Since they have never had caller ID with the DID analog trunks it is no big loss for now. I have a Definity tech who says he can make it work.
