In their own words
BulkVS SIP Trunking
BulkVS SIP Trunking provides SIP origination for inbound calls and SIP termination for outbound calls. It supports SIP-compatible switches, including Asterisk, FreePBX, FreeSwitch, Cisco Call Manager, OpenSIPS, and Kamailio, and reaches thousands of rate centers across the United States and Canada. Outbound calling uses the North American 1+ dialing plan, with STIR/SHAKEN enabled. BulkVS lists outbound calls at $0.004 per minute and inbound bundles as low as $0.0003. It says charges are based on minutes used, with no SIP trunk channel charge and no set contract. The service also offers number porting, emergency calling, toll-free numbers, and a SOAP/XML API for provisioning. For toll-free origination, the company says it can switch routing during higher-level carrier outages. Related services include CNAM, Robocall Mitigation, E911, STIR/SHAKEN, and 8YY services. It is available through web and API, with phone and email support. Pricing is listed from $0.06/mo, and there is no free plan.
