<p class="MsoNormal"><o:p> </o:p></p>
<div>
<p class="MsoNormal">I was configuring some new stuff for a customer recently, and as I was making test calls, I noticed the 7800/8800 series phones were not showing the Hunt Pilot Alerting Name like I'm used to.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I found a defect (<a href="https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvn39109"><span style="color:#0563C1">CSCvn39109</span></a>) which basically says that CUCM 11.5(1)SU5+ was updated to change the way it presents the Hunt Pilot
name to the phone, and the phone firmware has not been updated to parse it.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I implemented a SIP Normalization script on the SIP Profile applied to the phones, which rolls back the format to pre- CUCM 11.5(1)SU5.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">That Lua script looks like this:<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">M = {}</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New""> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">local function hunt_uri_rollback(msg)</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New""> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New""> local old_call_info = msg:getHeader("Call-Info")</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New""> local new_call_info = string.gsub(old_call_info, "huntpiloturi=\"%%22(.*)%%22(.*)\";", "huntpiloturi=\"%1\"%2;")</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New""> msg:modifyHeader("Call-Info", new_call_info)</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New""> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">end</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New""> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">M.outbound_INVITE = hunt_uri_rollback</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">M.outbound_UPDATE = hunt_uri_rollback</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New""> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">return M</span><o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Again, you apply it to a SIP Profile, which you then apply to the phone. Then restart the phone.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The Pre-Lua script Call-Info header looks like this:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">Call-Info: <urn:x-cisco-remotecc:callinfo>; security= Unknown; orientation= from; gci= 4-166949;
<b>huntpiloturi="%22Your Hunt Pilot Name%22<sip:\+<a href="mailto:16125551212@10.1.1.10">16125551212@10.1.1.10</a>>";</b> isVoip; call-instance= 1</span><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The Post-Lua script Call-Info header looks like this:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">Call-Info: <urn:x-cisco-remotecc:callinfo>; security= Unknown; orientation= from; gci= 4-166949;
<b>huntpiloturi="Your Hunt Pilot Name"<sip:\+<a href="mailto:16125551212@10.1.1.10">16125551212@10.1.1.10</a>>;</b> isVoip; call-instance= 1 </span><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Seeing the alerting name on the phone is a really useful feature in my opinion, and so I hope this helps you out until Cisco fixes this with a software patch.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">PS Make sure you have the CM Advanced Service Parameter set to True (default): <span style="font-size:12.0pt;font-family:"Arial",sans-serif">Display Hunt Pilot Name or DN for Hunt Group Calls When Alerting.</span><o:p></o:p></p>
