Open-source VoIP softswitch speaks GoogleTalk

April 17, 2006
Freeswitch, an open-source softswitch started earlier this year, leverages open-source software libraries and has recently added support for Google Talk. The codebase now includes Jingle (Jabber XMPP Voice) support with the addition of libDingaLing and mod_dingaling libraries. Jingle is an XMPP based protocol used by GoogleTalk. Using FreeSWITCH you can gateway GoogleTalk to SIP, H.323, or even the Asterisk IAX2 protocol. They also support Sangoma PRI cards and they recently announced support for secure RTP communication.

The libDingaLing library is currently considered to be in Alpha stage, but has been compiled and tested on many computer platforms including Windows XP, Solaris, Linux and MacOS X. The new endpoint module appropriately named "mod_dingaling" couples FreeSWITCH to libDingaLing and allows both inbound and outbound communication thus enabling GoogleTalk to gateway to the PSTN or to other VoIP protocols such as SIP or H.323. Looks like "Google Out" PSTN capability won't have to wait for Google to offer it themselves after all!

    You probably meant to link to freeswitch.org instead of freeswitch.com.

    Thanks for the news!

    If a "Google Talk Out" feature is all you want, there is a company called Talqer that already offers just that.

    Asterisk also offers a Jabber plug-in. There are actually several solutions for it, most notably app_jabber:

    Thanks for the info on this, Tom!

    From my review of Talqer, it appears to me to actually be using sip, not jingle, and just hacks into the gtalk client interface. As for the asterisk Jabber pluggin, I beleive this does not yet support jingle, just other jabber based text messaging.
