Connect your PBX to the network with limits you set.
Elastic SIP trunks for PBXs and contact centres, with channel limits, caller ID control and a CDR for every call.
Carrier-grade basics, without the paperwork
Registration and IP auth
Authenticate trunks by credentials or by allow-listed IP, with TLS and SRTP where your equipment supports them.
Channel limits
Cap simultaneous calls per trunk and per direction, so one runaway dialler cannot use the whole account.
Caller ID control
Verified caller IDs per trunk, with country-specific presentation rules applied for you.
Codec and DTMF options
G.711, G.729 and Opus [CONFIRM CODECS], with RFC 2833 and in-band DTMF.
Failover
Primary and backup signalling endpoints, plus automatic reroute when a destination route degrades.
CDRs and quality stats
Per-call records with setup time, duration, hang-up cause and quality metrics, available by API.
