How do I get e911 working on our PBX when some DIDs are with one carrier and other DIDs are with another carrier?
One option would be to look at e911 from clearlyip.com. We don’t require that your e911 services utilize our DIDs. https://kb.clearlyip.com/trunking/FreePBX-PBXact-Automated-Setup-with-Module.html#Managing_E911. Call-Back Profile and Dispatchable locations are managed independent of the provider that owns the DID. Only if you wanted to utilize the module for FreePBX and SMS Notification would you be required to have a DID from ClearlyIP.
