VoIP Gateways
VoIP Gateways
PSTN
If the voice signal originates from the PSTN, a VoIP gateway can convert the analog signal into packets of data and sends it to the IP-based phone system, and vice versa.
DIGITAL LANDLINES
If the voice signal originates from digital landlines, a VoIP gateway can also convert the digital signal into packets of data and allows the two networks to communicate.
CELLULAR NETWORK
GSM gateways convert GSM/3G/4G cellular connection to SIP and provide it as a trunk to an IP PBX system and the other way around.
Analog Extensions
