Desk to Desk calling with a premise peered SBC and another Telephony platform

[bksurfsup]

Hi there, wondering if anyone has managed to setup this calling method.

I have a peered an SBC using BYOC/P

I can call inbound to a Zoom users phone number when routing from the SBC.

I can not call inbound to a Zoom users extension number, I was hoping since the peering is configured on that account the calling to a Zoom users extension in the same account may also work. This would allow calling from another telephony platform connected to the same SBC without all Zoom users requiring a full number.

Has anyone managed to get this call type working?
