Re: [asterisk-users] transcoder
Can you describe in greater detail what you want to achieve? If you want something to take an incoming SIP INVITE, change the codecs listed in the SDP, forward the (new) INVITE to a media gateway, perform the reverse codec handling for the 200 OK and perform RTP transcoding on the resulting 2 legs of the call, it sounds like an IP PBX such as Asterisk would fit the bill, so are you asking for something different? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Khaled Chehab Sent: 04 February 2008 17:22 To: asterisk-users@lists.digium.com; [EMAIL PROTECTED] Subject: [asterisk-users] transcoder Dears Any one knows a standalone voip transcoder software name,not an ip pbx.

What exactly is an IP PBX? Certainly a stripped down Asterisk box can do what you want (as you described) and not qualify as an IP PBX. When does something become an IP PBX? When you load IVR, voicemail, conferencing, or some kind of complex dialplan?

Re: [asterisk-users] transcoder
Signalogic sells some hardware cards that utilize Texas Instruments DSPs to perform transcoding. Check out http://www.signalogic.com/index.pl?page=asterisk_ip_pbx. They supposedly have support for the rtpproxy module in OpenSER, so it makes a good external solution for transcoding. I haven't tried the cards out yet, but I'll post to this list again after we try out an Asterisk/OpenSER configuration. --Anish Basu ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [asterisk-users] transcoder
Asterisk can do it. You can purchase G729 license for about $10 per channel or you can buy one of these: http://www.digium.com/en/products/voice/tc400b.php they support G729 and G723 and they free up your CPU and then just get some PCI T1 cards. Or you can use a media gateway with G729 support... Cisco does... what sort of media gateway are you requiring?
