[asterisk-users] wav files are not playing asterisk

[Nikhil]

Hi

   I am using Asterisks as client. By console dial I can make calls. 
When do "dial s" from console it wil play demo files that I can here 
from headphone connected to asterisk running system(Android OS).If I 
play gsm file noise is coming,but asterisk is not playing wav 
files,below is the error I am getting. Where I can see the channels is 
encodes as GSM,and how to change to wav.?


*CLI> dial s

The 'dial' command is deprecated and will be removed in a future 
release. Please use 'console dial' instead.
