problem is related to an existing defect, CSCup16651, only this bug is filed under CIPC instead of the 88XX/89XX model. The defect describes the same output we’re observing on affected IP phones where console logs display “Max TCP connections reached” and
begin showing delayed processing of SIP transactions.<o:p></o:p></span></a></p>

don't stop ringing. The call is sent to an 8851/61 using INVITE, which means CUCM should force them to stop ringing on CANCEL.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">If this transaction occurs without issues, the problem is likely the IP phone and not CUCM, but digging in further would likely require review of console logs off the phone
to determine if the CANCEL was received and handled properly. If this transaction does not occur, then further review into SDL signaling would be needed depending on where the transaction broke.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Basic way to find SIP signaling to an 88XX is searching CCM SDL traces for "TCP message to <ip_addr_of_phone> on port" or "TCP message from <ip_addr_of_phone> on port". Console
logs would contain signaling info too and might be easier, but SDL of course is not written there.<o:p></o:p></span></p>
