Session Initiation Protocol Services

The issuing government authority located in Woodlands, Texas is seeking a vendor to provide session initiation protocol trunking and transport services, analog telephone services, and network on demand services. The agency needs to support staff operations, meeting rooms, and conference rooms across more than twenty-seven locations containing approximately 6,500 telephones. Having developed a Voice over Internet Protocol phone system for all users, the agency requires a solution that integrates with this system to support basic telephony features such as inbound and outbound dialing, voicemail, call forwarding, call transfer, caller identification, caller hold, and conferencing. The requested scope of work requires configuring trunks to support load balancing and automatic failover, with each trunk capable of supporting at least fifty percent of the total inbound and outbound call traffic at any given time. These trunks must allow local, long-distance, and international calls on the same trunk, and the agency requires long-distance codes for calls outside of the local area. The services must include emergency 911 calling, ten-digit inbound dialing, forwarding of alien telephone numbers, domestic and international calling, calling-party name and number delivery, and local number portability. Additionally, the vendor must provide web-based traffic, monitoring, and reporting tools to analyze historic usage, traffic patterns, and circuit utilization. Eligible bidders must be onshore organizations based in the United States, and the performance of the work will take place offsite. The agency is looking for proposals to establish the budget and requires local and long-distance usage package options, including bundled packages and per-minute pricing. Bidders must submit all questions regarding this opportunity no later than June 8, 2026.
