183 progress FileTrack uses with_loop(true) — short cues (beeps) repeat until answer

[autopeasant]

Summary

send_early_media_tone builds a FileTrack for progress audio with .with_loop(true).

Short cues (e.g. a generated double-beep WAV, or any brief prompt) therefore repeat continuously for the entire early-media phase instead of playing once. Operators hear “many beeps” rather than two.

Location

src/proxy/proxy_call/sip_session.rs — send_early_media_tone, progress-media FileTrack construction.

Expected

• Default for short progress tones: loop false (play once).
• Optional loop only when the configured progress/ringback asset is intended to be continuous (music-on-ring).

Suggested fix

.with_loop(false) for tone:// / explicit one-shot cues; keep loop only for ringback music files if desired (config flag).
