asterisk users - Aug 2008 - how to know what codec is being used

Hi,

how would i know what codec is being utilized? currently i have set allow=ilbc
disallow=all.
i unset all codecs on x-lite except ilbc.

i tried to make a call and look at the channel i see these. does this mean it is
using ulaw? how about writetranscode? does that mean there is no transcoding
happening on the call? call is going thru, rtp is also going thru. what i would
like to know is does it really use ilbc? i'm using 1.4.18.1. thank you


core show channel SIP/100009-082367b
? NativeFormats: 0x4 (ulaw)
??? WriteFormat: 0x4 (ulaw)
???? ReadFormat: 0x4 (ulaw)
?WriteTranscode: No
? ReadTranscode: No

Hello,

Try in ur sip.conf
disallow=all
allow=ilbc
"with this order" not sure if it may fix it.
