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.

I'm still seeing the odd instance of this happening, from looking at the user voice forum a few people are getting this issue intermittently.

    Have we checked the calling policies is there any custom calling policies or any changes to default calling policies??

      wildflavor  This was resolved  on the next day.  it happen on thurs/friday and was resolved on Monday.  No changes done on teams, it was self resolved and seems there was service interruption for short period of time.

       

      Sorry for late reply.

      I have the same problem. When I press resume nothing happens, no message on the SBC.  Call Transfer is working, Consultative Transfer is working.

        Hi Alex_Dunlop and Flavio_Goncalves! I am in the same boat! In another thread, I found could be de Call Parking Policy. Tried, no sucess. The interesting is when I do Consultive Transfer, the call goes normally to "hold" and I can resume It without problem!
