<div style="font-size: 12pt; font-family: courier,monaco,monospace,sans-serif;">I
fixed it the best I could (At least for SIP)<br><br>The stupid thing here is
that there really is an 8khz g722<br>and the moronic lemmings who would
implement the *wideband* version<br>to say 8000 despite the fact that they
*know* it is 16000 <br>and are too stupid to realize should be the ones to
suffer not us.<br><br>sigh,<br><br>I moved actual 8k g722 to payload 109 name
G722_8<br><br>and put 16k g722 on payload 9 by itself and added a hack to the
<br>sdp generator in mod_sofia to display 8000 <br><br>This makes my stomach
turn but I guess we must do whatever it takes<br>to preserve stupidity.
This makes me wonder if more of the SIP and SDP RFC's are just typo's which
would explain a lot....<br><br><br><br><br>

AM<br>Subject: [Freeswitch-users] G722 8000 vs 16000<br><br>
<div>Hi,<br><br>i want to use G.722 with its wide audio bandwith of 7kHz.<br>But
i have found that FreeSwitch resamples always from 16000 to 8000<br>Samples/s if
i connect a "standard device", i. e. a SIP device with a<br>"G722:9/8000" in its
SDP.<br><br>On the other side it is possible to use full bandwith if there is
a<br>"G722:9/16000" in SDP.<br><br>I think this is not correct!<br>FreeSwitch
should always use 16000S/s and also use "G722:9/8000" in SDP!<br><br>Read
RFC3551, 4.5.2:<br>...Even though the actual sampling rate for G.722 audio is
16,000 Hz,<br> the RTP clock rate for the G722 payload format is
8,000 Hz because<br> that value was erroneously assigned in RFC 1890
and must remain<br> unchanged for backward
compatibility.<br>...<br><br>I tried the 16kHz-implementation with a SIP phone
(siemens optipoint 410<br>with "G722:9/8000") and it seems to work.<br><br>In
the g722.h file is mentioned that the 8k option is used for fast and<br>flexible
interworking with narrow band telephony. I think this is a<br>special case (we
also support G711 for this). Our default should be<br>16000S/s and
"G722:9/8000".<br><br>What do u
think?<br><br>Thomas<br><br>_______________________________________________<br>Freeswitch-users
