BulkVS SIP Trunking review
A low-cost SIP option for North American numbers, PBXs, and carrier workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
BulkVS SIP Trunking provides inbound SIP origination and outbound SIP termination for enterprises, managed service providers, carriers, and PBX users. It supports local and toll-free numbers in the United States and Canada, with number porting, E911 emergency calling, IP-based authentication, SIP registration, and API-based provisioning. The service is a fit for organizations connecting SIP-compatible PBX systems, switches, or carrier platforms to North American calling services.
Pricing combines a $0.06 monthly recurring charge for inbound numbers with usage-based per-minute call billing. The published offering does not use a free plan or a fixed SIP trunk plan, and the pricing model is presented as contact sales. The vendor states that it does not charge for SIP trunk channels. Technical support includes G.711u, G.729a, T.38, RFC2833, and in-band DTMF, while E911 address verification and STIR/SHAKEN address operational and caller-authentication requirements.
Platform fit is a notable strength for teams working with established telephony infrastructure. Integrations include Broadsoft, Metaswitch, Sonus, ACME, Cisco Call Manager, Cisco Call Manager Express, Adtran, OpenSIPS, Kamailio, Asterisk, FreePBX, and FreeSwitch. A geographically redundant network and API-based provisioning support carrier and managed-service workflows, while local and toll-free number porting helps with migration. BulkVS is best suited to buyers focused on low-cost North American SIP deployment and usage billing. Organizations needing broader outbound geographic coverage or a simple packaged plan should consider alternatives designed around those requirements.
