Normally, MT Manager SIP proxy forwards incoming requests according to the domain name. Some SIP trunk providers or SBCs are not able to put the domain name in the request SIP messages. Instead, they always use the server IP address. In these cases, DID-based routing can be used to determine how to route incoming calls.
The DID-based routing option can now be easily managed via the MT Manager GUI.
- It is possible to enable and disable DID routing in the system. The default setting is Disabled.
- A new table under Settings -> DID Routing allows setting a DID or DID-range per tenant.
