The development of a PSTN media gateway is key addition to its service because calls initiated on Truphones IPnetwork can now be bridged to the PSTN. That means users of Truphonesmobile VoIP service can make calls to traditional land lines and viceversa. Calls originating from the PSTN are transcoded from G.711 to theAMR voice codec and bridged to IP.

The gateway uses SIP signaling toestablish and tear down the VoIP connections on the IP network and SS7signaling to initiate and release calls on theTDM Truphone selected TelcoBridges enabling technologies to build the carrier-grade PSTN media gatewaythey need, explained Gaetan Campeau, president, founder and EVP ofsales for TelcoBridges Inc., in a press release.
