2 issues
1st Issue Local voice reliability when traveling on the same Sim from Parcel to connected parcel Which happens when the Region/Sim/ Parcels all support voice and have it enabled While system shows that the voice is connected and each user will see both voice dot and graphic green lines indicating each is speaking will not hear any audio.
2nd Issue P2P calling or Private call does not work this is the same Problem that has existed since Beta testing of WebRTC Voice it goes Like this Caller A and Caller B will set-up a Private call (That we must do from the Profile because the call button in main UI or in IM depending on viewer does not work). Once we travel to another with Multiple parcels or teleport to Multiple sims that do not have voice enabled the Private call will fail and cannot re-established without heading to a Sim that supports voice after SL viewer or Firestorm viewer are completely restarted. Any attempt to re establish the call will be met with error message spam in IM or no connection at all.
Had a open ticket that falsely stated that these issues were resolved with a Patched 7.2,4 Firestorm but that is not correct
Made a New Support Ticket #2514236, but I do not expect a response since support never reaches out or responds.
