I have some limited experience in telco, and have done number porting in a business environment before.
I have a fairly large number of DIDs with a local telco provider that we use for inbound faxes. I am considering outsourcing to one of the various third party fax providers, but have been told that the numbers are not able to be ported.
I was under the impression that any number could be ported elsewhere these days.
Can anyone help me understand what would prevent a DID, or range of DIDs, from being ported? I don't understand whether this is a technical hurdle or a policy/procedural hurdle.
Thanks!
edit: Sorry, this is in the US, area code 662. We are not doing any sort of physical relocation, but perhaps that's why we might run into issues porting them from our current local dial tone provider to someone like eFax.
