I have found a couple of threads that list IP Addresses, but I continue finding more and I need to list them explicitly to allow for an API call to my VOIP.
Does anyone have a valid list of the IP Addresses active pieces uses so that we can pass them onto the TPA’s that we use.
The TPA I am using is VOIP.ms. I’ve requested an integration, but that doesn’t seem to be a priority so i’m left with listing IP Addresses to get the integration working through HTTP requests.
