The U1960 uses a highly-integrated SIP softswitch as the core and supports both narrowband and broadband services, helping effectively improve communication efficiency and reducing operating expense (OPEX).
The U1960 can connect to PSTN networks or dedicated network voice switches through digital, analog, and broadband SIP trunks.
