Description

If a new voice server is deployed (or the existing voice server crashed), the viewer does not reconnect to voice automatically. It remains disconnected, with no audible incoming voice audio from other users and 'Speak' button disabled in the UI. This persists until the avatar either moves into a new voice space or the user toggles the voice preference off and on.

I believe this is a viewer regression in 26.3:

• Testing with the 26.2.0.25021396775 SL release viewer, the 'Speak' button gets disabled when the voice server crashes, but becomes reenabled after the new instance comes up. After the recover, if either user speaks in nearby chat, all users see active voice indicators, but nobody hears any actual audio.
• Testing with Firestorm 7.2.4 (80712), the same system, the viewer always reconnects to voice without issue

Note that we've had this issue previously, as reported in #4743

Reproduction steps

1. Visit a region
2. Confirm that spatial voice is enabled and functional
3. Redeploy (or crash) the voice server
4. Note if the viewer reconnects to voice

Expected results:
The viewer should reconnect to spatial voice within a few seconds of the new voice server instance launching.

Actual results:

• The viewer simply prints that it disconnected from Voice, with no further updates:

INFO #Voice# newview/llvoicewebrtc.cpp(2729) breakVoiceConnectionCoro : Disconnecting voice.

• The 'Speak' button becomes disabled in the UI, and no Voice audio can be heard from other avatars.
• Other arriving users do not see a voice dot for the agent
