CUPC v7 Softphone shows as on phone but line still ringing
We have a small issue with Softphones at our remote sites.
We run CUPS 220.127.116.1100-18 and currently have the CUPC 7.0(2.13496) deployed.
At the main site internal and external calls work fine but when we are dialling internal extensions of users in remote sites the call is presented and rings in the headset but after the call is answered the line keeps rining in the headset. The Presence indicator shows that the user is on the phone, The user accepting the call hears ringing whilst the person dialing the call hears nothing.
DDI traffic (dialing the external line) works fine and can be traced back through the voice gateway.
I did a trace on the connection and the only thing that came back as suspicious was a STATUS: 489 event package not supported log.
