[cisco-voip] Ported to SIP carrier - some calls still coming in old carrier

[NateCCIE]

A lot of the time the loosing carrier doesn't remove internal translations,
so other customers of the losing carrier still come into the old PRI.
You'll need to ask them to clean it up, I don't think I have been patient
enough to see it be cleaned up by itself.

Subject: [cisco-voip] Ported to SIP carrier - some calls still coming in old
carrier

 

We ported about 700 DID's yesterday, from our PRI carrier to a new SIP
carrier. Everything is working great, except I still see some calls coming
into the old H323 gateways connected to the old carrier.  If I make a test
call from my cell phone to the called number seen on the old gateway, the
call routes through our new SIP gateway as expected.  Observing over the
past 2 days it does seem that some of the calls are from the same "calling
ID" and number.  

 

Could it just take time for the port to propagate to other carriers and this
will eventually work itself out over the coming days?  Or could there be
something else causing calls from specific callers to still route through
our old PRI carrier?

 

Thanks for any advice or knowledge you can share on this.

 

Sean.
