Microsoft Teams
Testing.
When a Microsoft Teams call drops, Microsoft points at the trunk and your carrier points at Teams, and you are stuck in the middle. Sipfront tests the real Teams calling experience over Direct Routing and Operator Connect, captures the Teams side and the SIP-trunk side independently, and shows exactly which one failed. Certify before go-live, monitor in production, end the finger-pointing. Powered by Probe and Lens.
Real Teams calls over your own trunks.
Sipfront places and answers real Microsoft Teams calls that traverse your Direct Routing or Operator Connect path, the same route your users take, and validates every leg of it.
Direct Routing calls
Inbound and outbound PSTN calls through your SBC into Teams. Validate routing, media and call quality end to end.
Operator Connect calls
Calls over your Operator Connect carrier. Confirm provisioning, routing and quality without waiting for a customer to complain.
Mid-call scenarios
Hold, blind and consultative transfer, call queues and auto attendant. The flows that fail in subtle, hard-to-reproduce ways.
Media path & codecs
SILK, G.722 and the negotiated media. Catch one-way audio, transcoding faults and media-bypass problems.
SBC & carrier failover
Force a failover between SBCs or carriers and confirm calls re-route cleanly, the path you hope never fires.
Real call quality
MOS, jitter, loss and post-dial delay on the actual Teams call, not a synthetic latency proxy.
Is it Teams, or is it the trunk? Now you can prove it.
Every Teams call has two suspects: Microsoft and your SIP trunk. Sipfront captures both legs independently and time-aligned, so a failure points at a cause, not at the other vendor.
Two-sided capture
The Teams calling leg and the SIP trunk captured in a single run, time-aligned, in one shared evidence format.
Fault isolation
See whether a 4xx/5xx, dropped media or degraded audio originated on the Teams side or on the trunk and SBC side.
Evidence for disputes
Hand your carrier or Microsoft a forensic trace and a recording instead of a screenshot. Disputes close in hours, not weeks.
Independent and neutral
Sipfront is neither Microsoft nor your carrier. The capture is the neutral source of truth both sides accept.
Drive a real Teams call, capture both sides.
From go-live certification to 24/7 assurance.
The same engine certifies a new deployment, gates every change, and watches production around the clock.
Certify before go-live
Validate a new Direct Routing or Operator Connect deployment, and the underlying SBC, before the first user ever calls.
Gate every change
Test each SBC firmware update, dial-plan change or carrier swap before it ships, not after a user reports broken calls.
24/7 monitoring
Beat places synthetic Teams calls around the clock and alerts on quality drift or hard failures before users notice.
Multi-tenant & partner
Certify Teams calling per customer tenant. Branded, signed evidence for the customers and carriers who ask for it.
Microsoft Teams Testing comes together on Carrier.
Browser-driven Teams calls (Lens) plus SIP-trunk capture (Probe) and 24/7 monitoring (Beat) line up on the Carrier tier. Same engine, same dashboard, same evidence format.
