Hi Fowler_23,
Yes I well aware of the SBC config for REFER. However we can see from SIP Signalling trace that the SBC didn't receive REFER on the wire. Unfortunately we are not able to do third party packet trace on switch or router as all the signalling are encrypted.

Hi,
Did you ever find the root cause for this issue? Experiencing this on two different tenants.
Seems we have the same issue. Was there any solution to the problem? We have Audiocodes as SBC vendor.
- I have same issue that Refer is not seen in SBC logs from Microsoft end, can you tell me how you solved this issue
