Ordinary calls working does not prove emergency calling is ready. On supported VoIP or SIP services, 933 provides an automated readback of the registered emergency address and phone number without reaching a 911 dispatcher. Confirm availability with your provider and check the information from each relevant device and location.
BCS recommends reviewing and retesting after installation, phone moves, number ports, and configuration changes. Also review direct 911 dialing, callback handling, emergency notifications, and power or internet backup separately: a successful 933 test does not verify every emergency function or establish compliance.

933 is for testing; call 911 for an emergency. Arrange any actual 911 test in advance through your local 911 center’s non-emergency number.

Many businesses continue to use legacy Nortel telephone systems for everyday communication. Business Communication Solutions (BCS) helps Austin-area organizations troubleshoot supported Nortel Norstar, Meridian, and Business Communications Manager (BCM) systems, including issues involving desk phones, extensions, call routing, and voicemail.
Whether you need to investigate a phone that is not working, make a programming change, or evaluate options for replacing an aging phone system, the first step is to assess your current equipment and configuration.
Norstar and BCM Troubleshooting: Investigate phone, extension, call-routing, and system performance issues on supported configurations.
Voicemail and Programming Support: Review available voicemail settings, extension programming, greetings, and call-handling requirements.
Hardware Assessment: Identify potentially faulty telephone sets, system components, or connections and assess suitable replacement options.
Phone System Migration Planning: Evaluate options for moving to a newer on-premises, hybrid, or cloud-based phone system while planning number porting and call-flow requirements.
Businesses comparing a newer hybrid phone platform can also explore the NEC SL2100 Hybrid Phone System.
BCS can help determine the appropriate next step for your existing Nortel system and discuss repair, maintenance, or migration options for your Austin business.
Replacement parts may be available through refurbished equipment suppliers and the secondary market. Availability depends on the Nortel model, component, and current stock. BCS can help assess the required part and possible replacement options.
BCS can assess voicemail and programming issues on supported Nortel configurations. The available reset process depends on the voicemail platform, system access, and current configuration.
These messages can have different causes, including programming issues, a faulty phone or station connection, or a system-side problem. The exact cause depends on the model and configuration, so diagnosis is recommended before replacing equipment.
Existing numbers may be transferable to a new phone service, depending on the carrier, account details, number eligibility, and destination provider. Number porting should be planned and confirmed before the migration date; uninterrupted service cannot be guaranteed.
The complexity depends on the existing Nortel platform, the number of extensions, call-routing requirements, voicemail, and the replacement system. Planning the configuration and testing important call flows can help reduce disruption during the transition.
Support depends on the Nortel model, software version, available interfaces, and carrier requirements. Some configurations may require compatible gateways or other equipment. Have the existing system assessed before selecting a SIP trunking solution.
BCS provides business telephone troubleshooting and support in the Austin area. Service availability and response times depend on the issue, technician availability, and the equipment involved. Contact BCS to discuss an outage and arrange an assessment.
