MS Teams Direct Routing - Internal call transfer failure
Hi all, My organisation is planning a move to direct routing. We have an AudioCodes VE SBC. I've been working on this for awhile and got everything to a pretty decent state. I've come across ...
No, not by rejecting the REFER with a response code. I basically did a message manipulation rule to re-build the Allow header for calls to MS Teams without including REFER. Which vendor are you using? If you have an AudioCodes as well, I can give you the rule syntax.
No, we're using a custom SBC, but yes, that was my second guess - to strip REFERs from packets. Thanks a lot, I'll give it a go and let you know if it works for me!
