This is exactly what I did. I used Xten's GSM driver to call a Zap extension. Readings where 100 Kbits/s. Using uLAW returned 80 Kbits/s !!!
I also downloaded Xten pro to test their g729 codec, readings were even worse. That's why I'm so intrigued. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of WipeOut Sent: quinta-feira, 30 de outubro de 2003 10:24 To: [EMAIL PROTECTED] Subject: Re: [Asterisk-Users] Sip bandwidth usage Paulo Mannheimer wrote: >That's weird.

If you ran iptraf an PC1 and made a call from PC2(X-Lite) to GS and your sip.conf entry for either have canreinvite=no then you will get double the traffic.. Best bet is to run iptraf on the Asterisk box and then make a call from the phone to Asterisk (eg to voicemail, echo test, the pstn or a Zap channel) so that the IP traffic is only one client making a call to Asterisk using the selected codec.. That should give you the best reading..
