Use a Cisco SPA8000 to bring analog phones or a legacy key system onto Resonance Telcom SIP trunks.
About Cisco SPA8000
The Cisco SPA8000 is an eight-port analog telephone adapter. It connects analog phones, or the line inputs of a legacy key system, to SIP services.
The SPA8000 has been discontinued by Cisco, but many units remain in service. It registers like any SIP device, so it can connect to Resonance Telcom with standard settings.
Why Resonance Telcom for Cisco SPA8000
- Keep analog phones or an older key system working without copper lines.
- Standard SIP settings for each of the adapter’s line ports.
- Engineers who can help you plan a replacement when the time comes.

Cisco SPA8000 FAQs
Can it connect a legacy key system?
Often, yes. The SPA8000 ports can feed the line inputs of many key systems, so the system sees ordinary phone lines while calls travel over SIP.
What if my SPA8000 needs replacing?
Because the SPA8000 is discontinued, plan for a current multi-port SIP adapter or gateway. Tell us how many ports you use and we will suggest options.
