Hello,

I'm looking for a reliable SIP trunk provider for Switzerland outbound calling with the following requirements:

DESTINATION:
- Switzerland (CH) termination
- Outbound only (no DID needed)

TECHNICAL REQUIREMENTS:
- CLI-enabled routes (flexible caller ID management)
- High audio quality (G.711 codec preferred if possible)
- TLS/SRTP encryption support (if possible)
- Stable routes with good ASR/ACD (if possible)

USAGE:
- Personal/business use
- Low volume (approx 5-15 hours per day)
- Single user

SETUP:
- Will self-host on own infrastructure (Asterisk/FreePBX)
- Need direct SIP credentials
- Prefer pay-as-you-go or prepaid

IMPORTANT:
- Must allow test calls (2-3 calls) before committing to credits

Budget: Open to reasonable rates for quality service

Please PM if you can provide this. Include:
- Per-minute rates

Thanks!
