Verify Phone LSC for MRA on Expressway

[STEFAN CHRISTEN]

Our customer requires that Phone LSCs are verified on Expressway-E when the try to register over MRA. In the MRA Deployment Guide there is only stated that this could be achieved with Mutual TLS. Has anyone implemented that yet? If so, can you please share the configuration?

The same Expressways are also used for B2B SIP calls. Hence the Mutual TLS configuration should not break the B2B functionality. As far as I have understood both B2B and MRA are entering on the Default Zone. So the Mutual TLS probably must be "enforced" using Default Zone access rules?

Any input is highly appreciated.

Many thanks in advance

For MRA Calls, last i was doing testing i found that any setting on default zone doesn't applies to such calls.

Basically i wanted to block the MRA Calls with specific patterns on Expressway and it wasn't working. So i am not sure if Mutual TLS will work with MRA.
