...when an incoming call is made from one of the towns local providers the caller gets a "this number is no longer in service" message. The best I can tell all other incoming/outgoing calls work fine.
I contacted voip.ms whose response was that the provider needs to update their routes. I contacted the provider (South Central Rural Telephone Co) and was advised:
"The VOIP service (Level 3) you have chosen to provide your parents service with has chosen not to get local interconnection with SCRTC to handle local calling service. We have addressed this issue with Level 3 in the past and they have chosen not to consider this. SCRTC has no way to complete the local call to that number. "
It appears that SCRTC is misunderstanding the issue. The problem is probably with their switch.
Once SCRTC ports the number out, when someone on the same switch dials your parents' number, the switch should see that the number is portable, check a database to see that it has in fact been ported out, and then send a query to get the LRN and SS7 point code of the switch to which it has been ported. Then it has to set up a route to the recipient switch and send your parents' number to the recipient switch. After that it's the job of the recipient switch to route the call.
The signaling should all be handled through SS7. To the best of my knowledge, having SS7 is a requirement for portability. As long as the recipient (Level 3) switch is handling incoming calls properly, the fault must lie in the SCRTC switch.
I don't think you've reached a person at SCRTC who understands the problem. You want to get the trouble sent to a person who handles switch translations
I have dealt with this issue before, with the ridiculous result that techs were checking at the NID to see what they got. Most likely you will have to get the trouble escalated. Technically since your parents are no longer SCRTC customers, one of SCRTC's customers should make a trouble report that they are unable to reach that number.
If local calling is regulated in your jurisdiction, the caller or your parents may also file a complaint with the public utilities commission or other state or local authority responsible for this regulation.--
