Oh. And to expect long delays as numbers (don’t) get ported. ☹

That’s the plan. Slow migration. Setup test inbound DID and use a different # 
to dial outbound for testing via SIP. Once everything is confirmed then migrate 
routing and port inbound DIDs.

The only thing I’ve heard and would probably keep is a couple of PRIs for

We are in the process of migrating for a legacy PTSN voice gateway (PRI) to a 
new CUBE based SIP connection to a iTSP connected via a private metro ethernet 
(not Internet based). Does anyone have a good source for recipes / dial-plans 
recommendations / best practices for this?
