About AT&T Synapse Small Business Phone Systems

The AT&T Synapse is a hybrid VoIP system for small businesses who currently have PSTN lines or a single T1/PRI line coming into their building who want to use the features of VoIP but are not ready to take the leap into hosted VoIP or SIP Trunking yet. For a fraction of the investment of a full VoIP System, a small business can install an AT&T Small business phone system with their existing LAN infrastructure and Public telephone lines and easily access Day, Night, and lunch auto attendant features and more.

The AT&T Small business system allows up to 100 handsets to be attached to the system, as long as they are all on the same LAN, and up to 39 outside lines for connectivity via PSNT or T1/PRI. 

Note: You cannot use 3rd party gateways, phones, or ATA's in this system. You cannot use AT&T's Gateways, phones, ATA's, or headsets in any other system. They will not work!
