[Asterisk-Dev] Is it a fault? H323 with GSM codec is not working

[Derek Smithies]

Hi,

I think that the gsm plugin is not being found by the openh323 library.

You will need to set an environment variable, PWLIBPLUGINDIR..

I have 

export PWLIBPLUGINDIR=$PWLIBPLUGINDIR:/home/derek/h323/openh323/plugins/audio/GSM0610
export PWLIBPLUGINDIR=$PWLIBPLUGINDIR:/home/derek/h323/openh323/plugins/audio/LPC_10

in an environment file, which I load before starting openh323 related 
programs.


Derek.
