In their own words
IPComms SIP Trunking
IPComms SIP Trunking connects a business PBX or session border controller to the public telephone network over the internet. The standard trunk has no per-channel fee or fixed channel count; concurrent calls depend on bandwidth and a fraud-protection limit that support can raise on request. SIP signaling is supported over UDP or TCP on port 5060 and TLS on port 5061, with G.711 μ-law, G.711 A-law, and G.729 codecs. IPComms lists two geographically separate US points of presence, inbound delivery to both, and automatic outbound failover. Trunks can use TLS signaling and SRTP media, and calls receive STIR/SHAKEN A attestation. The company lists compatibility with multiple PBX systems, Microsoft Teams Direct Routing, and contact-center connections. Its REST API supports number provisioning, trunk management, sub-account creation, and call-detail retrieval. Usage is billed from a prepaid balance. The service has a free plan, with paid service from $1.50/mo; E911 with a dispatchable location is available for $2.50 per number per month. A 30-day test trunk is available on request with limited call capacity and destinations.
