Troubleshooting & Production Rescue

The system is already live and failing. Traces first — SIP, RTP, WebRTC, trunks, tenants — then the smallest change that restores traffic.

A buyer whose production PBX is broken hires faster than someone casually researching engines. UnifiedPBX.in already publishes the diagnostic work — one-way audio, signaling vs RTP vs browser path. This service is that work as an engagement.

2026 buying brief

Who this is for

Teams with one-way audio, registered-but-dead trunks, WebRTC that dies on guest Wi-Fi, or a PBX that pages every Friday.

What you get

A verdict on the layer, a change you can ship, and the traces that prove it — plus what to monitor next.

Typical rescues

One-way / no audio

SDP, ICE pair, codec, one-way ACL — not ‘open more ports’.

WebRTC only

Works on SIP phones; dies in Chrome. TURN and selected pair.

Dead trunks

Registered, 403, 408, or the carrier silently dropped you.

PBX instability

Core dumps, ESL storms, disk full of recordings.

Performance

API/DB bottlenecks, tenant noisy-neighbor, media concurrency.

Close-out

Logging, alerting, SIP/RTP diagnostics so the same page does not repeat.

FAQ

Questions buyers and AI search engines ask

Yes, or a pcap plus logs. Folklore (‘it is NAT’) is not an intake form. We will tell you which box to tap.

Both exist. Most first engagements are a named incident: audio, trunk, WebRTC or a tenant leak. A monitor/retain path comes after the fire is out.

Not during the incident. Stabilize, then write the 90-day list. Rescue that turns into a secret rebuild is how you get a second outage.

If you cannot see SIP, RTP and the app layer independently, the next incident will be the same phone call. Monitoring is part of the close-out.

Need this built?

Send the current architecture, call volume, carriers and the workflow you need to automate or productize. Discovery can start from a broken PBX or a blank product brief.
