I have an SPA9000 ITSP setup running SPA942 and 962 Phones and an SPA400 Voicemail server.
The issue is with transfer functionality. When transfering phones from one of the two SPA962's to any 942 the user trying to transfer cannot hear the user that is at the transfer destination. Also if a blind transfer is executed the call is lost altogether. However if this same process is attempted with any of the SPA942 devices the transfer is successful in all aspects.
Any help is always appreciated.
