Hi Zhenhua,

Thanks for your reply..

I added the following code in /usr/share/alsa/pcm/modem.conf file...

1.
#
#Sample for using phone simulator
#
[phonesim]
Driver=phonesim
Address=127.0.0.1
port=12345

-----------------------------------------------------------------------------------------------------------------------------------------
I tried to ./list_modems. I got nothing on command prompt. According to my knowledge i should get the available modems (atleast phonesim0)
I tried to enable  the modem using the following command..

./enable-modem /phonesim0

I got 
output as follows...

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Connecting
 modem /phonesim0...

Traceback
