In their own words
Callcentric SIP Trunking
Callcentric SIP Trunking's Pay Per Call plan lets businesses place worldwide calls from SIP-based IP PBXs or gateways. The plan has no monthly fee or included minutes; outbound calls are charged at variable per-minute rates, while calls to other Callcentric members are free. It includes three channels, allows unlimited maximum channels and charges no additional channel fee. An account deposit can be as low as $5.00. Business numbers are available in the USA, Canada and over 35 other countries. Listed uses include offices, call centers, IVR services and calling card providers. Callcentric says most SIP/2.0 hardware and software should be compatible, and names 3CX, Asterisk, freePBX, Bria, ZoIPer and LinPhone among options users have used. Compatible devices need specified SIP, RTP, authentication, proxy, DNS and codec support. The service supports Android, iOS, Linux, macOS, web, Windows, extensions and self-hosted setups. US/Canada toll-free numbers are listed at $3.95 setup and $3.95 per month.
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.
