OK, I've got a CCM with H323 trunk to CME to get out. CME is providing SIP trunk out to provider. I use a CIPC on my laptop registered to CCM to call my cell phone. I place call on hold, I hear music. I resume the call and I can talk to myself. However, I can no longer place myself back on hold. When I press the "hold" softkey, it does nothing and a few moments later it ends the call. Anyone ever seen this?
