<p class="MsoNormal">Hi, guys and gals.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a customer with a CUCM 9.0(2) cluster.<o:p></o:p></p>
<p class="MsoNormal">It is connected to a SIP PBX via a direct SIP TRUNK (No SBC, CUBE or otherwise). The PBX has four different nodes, all configured in the SIP TRUNK<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">They claim it was working fine until last Thursday, where they did an upgrade to one of the nodes of the PBX. After that, calls going from PBX to CUCM fail with a 488 Media Not Acceptable error.<o:p></o:p></p>
<p class="MsoNormal">They also have tried making calls from one of the not upgraded nodes, with the same error.<o:p></o:p></p>
<p class="MsoNormal">I have been looking into the SIP traces, and I see nothing really telling of a problem there.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We reseted the SIP trunk with no success.<o:p></o:p></p>
<p class="MsoNormal">I have looked at the región configuration, and all regions are set to the System Default (G722, G711)<o:p></o:p></p>
<p class="MsoNormal">I also tried changing the preferred codec in the SIP trunk, with no success.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Following this, I am pasting the SIP messages of a failed call from PBX -> CUCM and a successfull call in the reverse, from CUCM -> PBX.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can you see if anything is wrong or odd?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Regards,<o:p></o:p></p>
