Please help me to solve this issue…

Thanks

read your error messages … you might think you are only using passthrough, but your Asterisk box is trying to translate sound files in GSM to G723 and can’t … and nor can it find G723-encoded versions of the sound files it’s trying to stream.

you either need the codec, or the sound files encoded using the codec.

Hello,
Thanks for your reply …i think i need special sound files…rt? .where will i get the sound files for g723 ?..pls give me the link …i want just passthrough option …is there any special configuration for that.?

Thanks.

search the wiki, you’ll find details of free converters and instructions on how to use them.

as for the link to the wiki, you read the sticky at the top of the forum didn’t you ?
