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

[Riley, Sean]

Thanks for the toll free suggestion Loren.  I have identified a couple of toll free numbers we have, and they are routing into the old PRI.  I had not even thought about those.

However, there are still some calls hitting it that are not toll free routing.  Seems others have suggested internal translations inside the old carrier as well.  I will be reaching out to them to see if that is the cause.

Sean.

I’ve seen this with toll free numbers that deliver a local DID in, so you don’t know what the toll free being dialed is.
If you don’t have local records you will need to go to your toll free carrier (might not be the same one that owned the PRI) and request reports of all TFNs owned and what they point at or what they deliver to you when dialed.

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.
