Cannot resume/end pstn call that has been placed on hold?
I managed to resolve this issue by working with the SIP carrier, they hadn't approved Teams on their trunks so we had to start from scratch and now have a working config.
On our Audiocodes SBC I have the SIP Trunk IP profile set a specific way for hold and retrieve, see attached screenshot.
There is still a time delay when resuming a call but this is an MS issue that they are aware of.
Further to this, after much testing and tweaking i've now managed to get a little further. After changing some options in the SIP trunk IP Profile i've now got hold and retrieve working, but i don't get music on hold now.
I'm pretty sure this is a SIP trunk issue, i've reached out to the carrier to see if they have any ideas.
I've put a screenshot down below of the IP profile tweaks i've made.

Do you have any updates?
After working with MS for 4 months on this issue the L2 telsl me that they are aware of the issue and it is on the roadmap. Hard to tell if the tech is providing the truth or BS.
We are definitely frustrated with a Beta product being released to their users and having us debug their software for them. Have tested a different HPBX Product and will probably migrate by end of month.
