IPComms SIP Trunking
Acworth, Georgia, USA
What it 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, though concurrent calls depend on bandwidth and a fraud-protection limit that support can raise on request. SIP 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. The service lists two separate US points of presence, inbound delivery to both, and automatic failover for outbound calls. Trunks can use TLS signaling and SRTP media, and calls receive STIR/SHAKEN A attestation. Listed PBX compatibility includes Asterisk, FreePBX, 3CX, Cisco CUBE, and others; integrations include Microsoft Teams Direct Routing and contact-center services. A REST API supports number provisioning, trunk management, sub-account creation, and call-detail retrieval. Usage is billed from prepaid balance, with paid service from $1.50/mo. E911 with dispatchable location is available for $2.50 per number per month.
