Truphone has selected FreeSWITCH’s and TelcoBridges’ carrier-grade telephony platform to enable VoIP calls on mobile phones, the companies said Tuesday.
Truphone is a mobile Internet network operator that brings VoIP to mobile phones via WiFi using SIP. The three companies collaborated to port FreeSWITCH’s open source telephony application code to TelcoBridges’ hardware platform and have adapted to fulfill Truphone’s requirements for a media gateway, bridging calls between the Internet, using VoIP and the PSTN.
Calls originating from the PSTN must be transcoded from G.711 to the AMR voice codec and bridged to IP. The media gateway uses SIP signaling to establish and tear down the VoIP connections on the IP network and uses SS7 signaling to initiate and release calls on the TDM side.
