MEMORANDUM

6 November 2026

From: Code 10 To:027

Subj: RECOMMENDATION FOR OTHER THAN FULL AND OPEN COMPETITION

Regulatory Authority: FAR 13.106-1(b)(1)

Ref: (a) N63394-26-SIMACQ-BD3-0075 Command Landline (Code 104)

l. It is recommended that the Government acquire continued Command Landline MPLS/SIP services from AT&T for a 12-month period, from 1 January 2027 through 31 December 2027.

The estimated total value is $133,718.52. The requirement will be funded with NWCFCST funds and has no option periods.

The requirement supports uninterrupted enterprise Session Initiation Protocol (SIP) voice services and associated private-network transport for Naval Surface Warfare Center, Port Hueneme Division (NSWC PHO). Required services include approximately 400 concurrent call sessions, approximately 4,000 Government telephone numbers, private transport and connectivity, carrier routing, managed network services, local and authorized long-distance calling, service restoration, 24-hour/7-day escalation, incident response, and configuration control.

The requirement also supports the existing SIP-based communications path used by building fire-alarm panels to transmit alarm, supervisory, and trouble signals to the designated monitoring location. Any material change to carrier routing, SIP configuration, voice-gateway interfaces, or related communications services that could affect fire-alarm reporting requires coordination with NSWC PHO Telecommunications/Information Technology (IT), Base Fire/Safety personnel, and the Fire Protection Engineer.

This action is limited to continuity of the current operational environment while NSWC PHO completes transition-readiness actions and conducts competitive acquisition for long-term SIP services. The bridge requirement excludes cellular services; Emergency Responder/Intrado Emergency Responder Service; Location Manager; dynamic emergency-location services; fire-alarm modernization; and new alternate fire-alarm communications architectures. •

2. AT&T's existing SIP trunking, private transport, carrier routing, telephone-number services, and managed network configuration are integrated with the NSWC PHO Government voice environment at the established network demarcation point. Continued service must remain compatible with current SIP signaling, voice-gateway interfaces, call routing, telephone-number assignments, carrier transport, and Government-managed voice infrastructure.

The current configuration also supports the fire-alarm communications path. NSWC PHO and AT&T recently remediated that path through conversion to SIP signaling, voice-gateway modernization, carrier-capacity improvements, and routing corrections. Following the remediation, the Government completed supervisory, trouble-reporting, and failover testing without reported communication dropouts, alarm-acknowledgment delays, or signaling errors.

An award to another provider for the bridge period would require a carrier transition, including establishment of replacement transport and carrier demarcation; configuration of replacement SIP routing; reconciliation of telephone numbers, billing-office exception assignments, account records, and noncontiguous number groups; submission and management of Local Number Portability actions; revalidation of the fire-alarm communications path; end-to-end cutover and acceptance testing; and development of rollback procedures.

These activities cannot be completed before the required period of performance without unacceptable risk of service interruption, porting delays, duplicate-service costs, and degradation of mission, emergency, and life-safety communications. AT&T is therefore the only source capable of continuing the currently installed and operational configuration for the limited bridge period without an immediate carrier transition.

3. Market research was conducted through Sources Sought Notice No. N63394SIMACQ2601, posted on SAM.gov from 4 August 2026 through 17 August 2026. The notice sought capability information for an enterprise SIP trunking solution supporting approximately 400 concurrent call sessions, 4,000 Government telephone numbers, private transport, Local Number Portability, life-safety communications, Emergency Responder integration, and transition from the incumbent provider.

The Government received responses from MetTel, Cytranet, NT Connect, T2 Technologies, KriaaNet, and AOC Connect. Granite Telecommunications subsequently provided capability and pricing information and participated in technical-requirements discussions. These responses demonstrate commercial interest and potential capability to compete for a future long-term SIP-services requirement.

The alternative approaches generally contemplated a full carrier transition, phased number porting, legacy Centrex/life-safety-line modernization, Emergency Responder integration, wireless or cellular-enabled fire-alarm communications, or another replacement architecture.

Those approaches do not meet the immediate bridge requirement, which is limited to continued operation of the existing AT&T configuration and excludes cellular services, Emergency Responder integration, fire-alarm modernization, and a new alternate fire-alarm architecture.

Market research therefore supports a future competitive acquisition but did not identify another source capable of assuming the current operational environment within the required timeframe without transition actions that present unacceptable risk to mission, emergency, and life-safety communications.
