Our normal WAN is MPLS, backup is DMVPN over the internet. The 9951s randomly unregister when the handset is picked up, when speaker phone is attempted to be used, etc. The rest of the phones are 6945s and SCCP. We have 0 issues with call control, voice quality, etc, etc with the 6945s and when the 9951s are registered calls complete and sound fine but they often de-register and since we like to use these for receptionists have issues with call flow.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Is there some sort of keep alive timer that affects these models that we should adjust?
