Hi is it possible to use freeswitch as media gateway in which freeswitch is used just for transcoding between g711u and g729? I need this to be able to use g729 codec available on linux because my main freeswitch box is based on windows(all registration info must be on this machine) and I've got a limited bandwidth to handle 10 concurrent calls so I need to have such thing call -> fs(windows)->g711->fs(linux)->g729->ip phones(7941) thanx

Specifically, look at mod_com_g729 or Sangoma cards for g729 transcoding support. You can then set your profile to allow G711 on incoming calls and specify G729 on outgoing calls either on the profile or using the absolute_codec_string variable. FS will then convert between the two for you. Free versions of g729 are not available unfortunately, for patent licensing reasons. -Steve On 24 July 2010 17:31, babak yakhchali <babak.freeswitch@gmail.com> wrote:

how can I force windows side freeswitch to send calls through linux fs box? I mean registrations are sent to windows box so how should I call bridge application to send calls through linux box which g729 licenses are available on thanx
FS still needs to see the signalling to start up the call. You'll need to bridge the call from the Windows FS to the Linux FS, and then have Linux FS send the call on to the final destination either directly or via the Windows FS by bridging back to it (but on another profile/dialplan/extension so it knows it's to send out to the phone not to the Linux FS). Client ----(g711)----> Windows FS ----(g711)-----> Linux FS ----(g729)----> IP Phone Client ----(g711)----> Windows FS ----(g711)-----> Linux FS ----(g729)----> Windows FS ----(g729)----> IP Phone Directly from Linux FS to phone would be optimal, but you'll need to do it via the Windows FS if you're using the registration data to know where to send the call to. Using bypass_media would allow you to avoid sending media via Windows FS which'll massively reduce the server load. SIP signalling uses hardly any CPU since there are very few messages during most calls. You'll get the following paths: Signalling: Client ----> Windows FS ----> Linux FS ----> Windows FS ----> IP Phone Media: Client ----(g711)----> Linux FS ----(g729)----> IP Phone -Steve On 24 July 2010 19:10, babak yakhchali <babak.freeswitch@gmail.com> wrote:

is it possible to use just one database to store registration data for multiple fs boxes? I mean both linux and windos fs use same registration data

if my both ends support g729 can I record using record_session in g729 format and later convert it to something else?

Instead of sending tons of questions to the mailing list why don't you just join the #freeswitch irc channel on irc.freenode.net. That way you can ask your questions and discuss them in real time. You may also want to search wiki.freeswitch.org before asking. Just a suggestion. Regards, Patrick
