Request a quoteQuestions engineers ask first
Anything else goes into the setup call.
Is it SaaS or on-prem?
Fully managed on our infrastructure, EU-hosted by default. Dedicated or single-tenant nodes are available for selected deployments.
Which audio codecs?
Opus Stereo (48 kHz) and Opus Mono, plus G.722 for hardware codecs that need it. The iPhone app runs Opus only. DTMF via RFC 2833. We do not carry G.711 or narrowband telephony codecs.
Is it EBU Tech 3326 compatible?
Codecs that follow EBU Tech 3326 connect over standard SIP and talk Opus or G.722 with MosiSIP. It is not a full 3326 profile: G.711, MPEG Layer II and linear PCM are not offered.
What about NAT and symmetric carriers?
Static-IP codecs simply register. Behind symmetric NAT we ship a preset with max_contacts=1, contact rewrite and TCP/TLS transport, with re-register around 50 s.
Can I keep my PBX or carrier?
Yes. Register codecs directly with MosiSIP or trunk to your existing SIP infrastructure. External trunk calls are marked on the dashboard.
Which SRT encoders work?
Any standard SRT encoder in caller mode, including OBS, ffmpeg, hardware and bonded uplinks. AES-128 and AES-256 passphrases are supported.
How low is the latency?
On clean networks a few seconds glass to glass, under 3 s with low-latency HLS. It depends on encoder, path, ARQ settings and the browser.
What happens if a feed drops?
Push two independent streams. The player shows both with live status and switches with one click, without a page reload.
What can I export?
Live SIP signalling, registrations and per-call RTCP plus the quality index, as JSON at /api/status. Per-call PCAP export on request.
