[cisco-voip] SIP-SCCP Hold Resume Issue

[Carlo]

I ran into a similar problem. went from a SIP gateway thru a ICT to a SIP phone. When they transfered the call to a sccp phone, the caller would not come off of hold until i put the call on hold from the sccp phone and then resume.

This is a problem with 8.6.2 older version.  Update to the latest version

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.
