Hi UniMRCP Support Team,
We’re troubleshooting an integration where UCCX talks to UniMRCP (masquerading as LumenVox)
and UniMRCP fans out to local Azure Speech containers (STT/TTS).
RTP clearly reaches UniMRCP, but recognition consistently ends with no-input.
Details below, plus a call log attached.
Environment / versions
- UniMRCP Server: 1.7.0
- SofiaSIP: 1.12.11-239-g54ef3e2
- APR: 1.5.2
- Azure STT plugin (umsazuresr): 1.32.0
- Azure TTS plugin (umsazuress): 1.25.1
- Licenses: SR 2 ch, SS 4 ch
- OS: Debian-based VM; packages upgraded via apt-get to latest available
Architecture
- UCCX → UniMRCP (we present as “LumenVox Media Server” because UCCX doesn’t support UniMRCP server directly).
- UniMRCP → Azure local
containers
- STT endpoint(s): http://localhost:5001 / http://localhost:5002
- TTS endpoint: https://eastus.tts.speech.microsoft.com/cognitiveservices/v1 (for now until we will install a local container)
What works
- SIP/MRCPv2 signaling is clean. Channel comes up, grammars are defined, and RECOGNIZE requests are accepted.
- RTP session opens: UniMRCP answers with PCMU/8000 (recvonly).
- We captured the RTP stream at the UniMRCP host and can play it in Wireshark, you can clearly hear “yes” / “no”.
- The Azure STT WebSocket session is established and upgraded (101 Switching Protocols).
Symptoms
- Despite RTP arriving,
the UniMRCP log shows:
- Input Complete [success] size=0 bytes, dur=0 ms
- Followed by RECOGNITION-COMPLETE ... Completion-Cause: 002 no-input-timeout
- Periodic warnings appear
when MRCP messages are received (from UCCX):
- WARN Cannot read the
first field in start-line
(Messages still seem to be processed, grammar loads, recognize starts, so unsure if this is benign parsing noise or relevant.)
- WARN Cannot read the
first field in start-line
Evidence from logs (high level)
- RTP receive: e.g., Open RTP Receiver 10.80.64.150:4002 <- 10.80.60.105:25308
- Media path: Source->[PCMU/8000/1]->Decoder->[LPCM/8000/1]->Bridge->[LPCM/8000/1]->Sink
- Files opened (for debugging): both 8 kHz and 16 kHz WAV writers open, and a resampler to 16 kHz is created for the Azure STT container.
- VAD: start-of-input=internal, noinput-timeout=10000 ms, VAD mode 0; yet recorded size remains 0.
Config highlights (current)
- SIP transport: TCP 5060.
- MRCPv2: passive setup on server, port 1544.
- RTP: PCMU/8000 and telephone-event advertised; jitter buffer enabled; ptime 20 ms.
- Profiles: speechrecog → Azure-SR-1 (umsazuresr 1.32.0); speechsynth → Azure-SS-1.
What we’ve already tried
- Verified audio path with PCAP (playable, intelligible).
- Reduced advertised codecs to PCMU + DTMF.
- Cleaned up unimrcpserver.xml to remove non-schema elements; resolved earlier config warnings.
- Upgraded UniMRCP modules (now on umsazuresr 1.32.0; TTS remains 1.25.1).
Questions for your guidance
- VAD / audio handoff: Given that RTP is received and decodes to LPCM, what would cause size=0 bytes on the recognizer side? Any known issues in umsazuresr 1.32.0 with μ-law 8 kHz input, internal VAD, or resampling to 16 kHz before sending to Azure?
- MRCP parse warnings: Is Cannot read the first field in start-line expected with UCCX’s MRCPv2 framing, or does it indicate a line-ending/BOM/framing quirk that could influence VAD or timing?
- Best-practice knobs:
- Should we set start-of-input = external and rely solely on UCCX’s START-INPUT-TIMERS, or keep internal?
- Any recommended VAD parameters (e.g., thresholds, leading/trailing silence) for 8 kHz μ-law from Cisco gateways/UCCX?
- Any reason to prefer InputFormat over AudioFormat for STT in 1.32.0?
- Codec/ptime: Are there known corner cases with UCCX offering sendonly PCMU and UniMRCP answering recvonly that would require adjusting ptime, jitter buffer, or SOA settings?
Attachments
- uniMRCP_Log_9-May-2025.txt (full call flow showing RTP open, RECOGNIZE, VAD/no-input)
- PCAP of the call (available on request)
Any pointers, known issues, or recommended config tweaks would be greatly appreciated.
We’re happy to provide additional traces/configs as needed.
Thank you,
Dani
