Commetrex Introduces Addition of V.34 Support to BladeWare HMP

By Anuradha Shukla, TMCnet Contributor

Commetrex, a specialist in IP fax technologies and the company credited with T.38 fax termination, has announced that its BladeWare HMP telephony platforms now come with support for V.34 G.711 passthrough. Thanks to the inclusion of this support, BladeWare users may choose to use V.34 to complete IP fax calls, a process that takes only half the time as compared to fallbacks to V.17 speeds.
T.38 is the current international standard for fax taking place using IP networks, or FoIP, while V.34 is the fastest fax modem used nowadays. Few T.38 Version 3 V.34-capable gateways exist in the market today, and none are deployed in carrier networks. As a matter of fact, many VoIP service providers do not yet support T.38 at all. BladeWare is able to help by offering users the ability to deliver faxes with only half the connection time of any server available today.
Tom Ray, chief marketing officer of Commetrex (News - Alert), explained that the company itself makes use of the services of all-IP managed-service provider Cbeyond-more specifically a clear-channel IP pipe connected to Cbeyond's (News - Alert) metro network-for its communications.
These, however, do not support T.38-all faxes utilize G.711 pass-through modems including V.34 and are virtually error free. Rounding up this solution is a BladeWare-based server that is set up to make use of Cbeyond's SIP trunking.
Ray added that many vendors may claim that the G.711 pass-through fax technology does not run on carrier networks. While Commetrex does not dispute that many carrier networks indeed cannot reliably support faxing, the company says that there are many that do.
To take advantage of this higher speed, BladeWare with V.34 support is a requirement. LAN-based applications where G.711 works well, such as those incorporating IP PBXs without T.38 compatibility as gateways between enterprise fax servers and PSTNs, are also available.
Those solutions make use of an IP connection over a high-performance LAN. In this solution, no packet loss has to be dealt with, and, thanks to the exclusive PCM-clock management software that Commetrex offers, even the longest G.711 faxes can come through perfectly.
In related news, Clarus Systems (News - Alert) recently enhanced IP Telephony testing performance.
