Frequently asked questions
Yes. One-way and no-audio problems are usually in the RTP media path or NAT/SDP handling rather than the signalling. With a SIP trace and the SDP from each leg, the media direction can be followed to the point where it stops.
Yes — Asterisk, FreeSWITCH, Kamailio, OpenSIPS and RTPengine. Many real systems combine them (edge proxy, media relay and application logic), and problems often live at the boundaries between them.
WebRTC-related work may be reviewed separately where it is directly connected to Asterisk, Kamailio, RTPengine or SIP troubleshooting, but it is not currently offered as a standard fixed-price service.
Reading traces is central to how Zypager works. A clear pcap, sngrep or Homer export, plus call details, is often enough to identify the failing transaction without live access.
Yes, on an hourly basis for urgent incidents — failed inbound/outbound calls, RTP/no-audio and carrier problems. Final scope and availability depend on access and complexity.
