I have a Cisco ATA192-MPP that I am managing thru Teams to connect up a phone line to a Valcom Over Head Paging System. I have several of these using the same setup running without issue. My most recent site however is wanting to use the OHP to deliver safety presentations, HR info talks, etc, which often last multiple minutes. Unfortunately, the call seems to drop after 5 minutes consistently, requiring the initiation of another call to continue. I have verified the settings for the paging system with the vendor as well as the user settings in the Teams tenant, with everything set as it should be. My next check is with the ATA settings (which I am really not familiar with). In the Teams tenant, this is set as a SIP device. I have looked at the various settings for voice on the ATA, but I do not see anything related to something like "idle time out" or "max call time". Any suggestions would be much appreciated!
