<p class="MsoNormal">Hi,<span lang="IT"><o:p></o:p></span></p>
<p class="MsoNormal">we have a Call Manager Cluster 8.6.2, and at a remote site we have both Cisco SCCP Phones and SIP Phones, some SNOM 300 and some Gigaset DECT Phone. All of them are correctly registered on the call manager (connection between the remote
site and the Call Manager is made via MPLS), can call each other, no partition applied, same device pool, no css applied. During calls between the SCCP and SIP phone, if the SCCP endpoint hold the call and then resume, the SIP endpoint does not correctly process
the resume: it still hears the hold tone, while the SCCP phone can hear the SIP audio as if the call has been resumed but just on one side. In this situation, also, if the SIP hold and resume the call, everything come back to normal.<span lang="IT"><o:p></o:p></span></p>
<p class="MsoNormal">No hold/resume problems between SCCP and SCCP phone, and no problems between SIP and SIP phone.<span lang="IT"><o:p></o:p></span></p>
<p class="MsoNormal"> <span lang="IT"><o:p></o:p></span></p>
<p class="MsoNormal">Do you have any suggestion about where could be the problem or how to do a better troubleshooting?<span lang="IT"><o:p></o:p></span></p>
<p class="MsoNormal">Thanks in advance<span lang="IT"><o:p></o:p></span></p>
