My org has two separate VoIP providers. One provider that is set up with our corporate PBX system (a 3rd party cloud system we don’t have any control over) and another that is tied to an Asterisk instance we set up in the AWS cloud.
A few months back we ported a local number from the 1st provider to the 2nd.
Based on some issues we’ve been trying to track down, it seems that even though the number was ported to carrier 2, it seems like some carriers are still routing calls to the number in question to carrier 1.
Is there some kind of tool I can use to check on the “routing” for this number from various carrier viewpoints? In the networking world, I would use a looking glass server at various ISPs to get info on routing for a given IP address. Is there something similar I can use for a phone number?
I don’t believe there are any public facing tools to see carrier routing. Sure would be nice, if there are any please post them here! I have seen where a losing carrier does not tear down their translations which causes the situation you describe. Comcast was real bad about this a couple of years ago. Have you reported this issue to carrier 2? As the winning carrier in the number port, it is their responsibility to make sure the port is complete and to contact the losing carrier if necessary.
No I haven’t reported it because I wasn’t sure how this all worked, but will do so.
Could be a few things. Do a caller ID lookup and see who the number is showing registered to. Make sure the number is removed from the pbx it moved from. If it’s showing the correct carrier and the number isn’t in the original pbx routing table. If that’s all clear than it’s the winning carrier NOC team you’ll need to talk to.
