This makes me wonder if more of the SIP and SDP RFC's are just typo's which

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
