STATUS_CTX_MODEM_RESPONSE_VOICE
The remote endpoint answered as voice, not data
This status means the modem path heard a voice answer or voice-class response where a data modem negotiation was expected. The remote number may be wrong, routed to a voice line, or answered by a non-modem device.
The RDS stack has not yet reached a normal Remote Desktop session. Troubleshooting should start with dialing rules and endpoint identity, not with session-host application behavior.
What to inspect
- Confirm the dialed number, PBX route and outside-line prefix.
- Check whether the target modem is powered on and configured for data mode.
- Compare manual dialing behavior with TAPI/RAS logs.
