Try rebooting the server or stopping and restarting asterisk. Sometimes a "sip reload" or "reload" does not completely reload everything.

I have seen on rare undisplayable characters sneak into a config file and screw things up.

hi i already done restarting the asterisk server several times...but still the same....problem..

[mcargile]

First off which version of Asterisk are you using?

Also try passing the file through the command line tool dos2unix. It does a pretty good job of removing characters that Unix systems think of as strange.

If that does not work try editing the file with mc (midnight commander). It is fairly good at displaying odd characters and letting you delete them.

If that does not work move your sip.conf to like sip.conf.back and recreate it by hand on the linux command line. This will insure that no strange character sneak into the file.

If that does not work there may be a bug in asterisk.

I guess its not best thing to say but asterisk still used the rfc2833 as default so operational point i think you wont face any issues with it....

[williamconley]

what method are you using to edit the .conf file? i've found that some windows editors will put the wrong line endings in and cause the last character to be deleted. opening the file in a linux text editor and re-saving it can help. just a thought.

thanks all...i got it....its with the sip.conf two user missed the input dtmfmode=283...just correct it with rfc 2833..
