IPComms SIP Trunking
What IPComms SIP Trunking is
IPComms SIP Trunking connects a business PBX or session border controller to the public telephone network over the internet. Its 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. The service supports SIP 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. Listed PBX compatibility includes Asterisk, FreePBX, 3CX, FreeSWITCH, FusionPBX, Cisco CUBE, Avaya, Yeastar, Issabel and Kamailio. It also lists Microsoft Teams Direct Routing and contact-center connections, plus a REST API for number provisioning, trunk management, sub-accounts and call-detail retrieval. Usage is billed from a prepaid balance. A free plan is listed; paid service starts at $1.50/mo. E911 with a dispatchable location is available for $2.50 per number per month.
