So I tried same thing on fs_cli and netcat.

from fs_cli executed following command:

originate sofia/internal/1000%192.168.1.94 &socket(192.168.1.94 9050 async full)

I did a netcat: on 192.168.1.94 9050.

when the extension 1000 answered, I did connect\n\n , myevents\n\n and sendmsg command to answer (i.e.  answers\n\n).

now if I execute api uuid_setvar uuid x 30 or  api uuid_getvar uuid x; 

I am getting -ERR command not found.

if I do same stuff on outbound socket created when extension 1000 dials in to extension 1021.

and I setup dialplan to created outbound socket

application=socket  data="192.168.1.94L9050 async full"  I could do api commands. What is the difference in both outbound sockets?? except one is created using originate other is created when dialed in. 

My intension is to dial a phone number, do play_and_get_digits and do get the digits pressed by user using uuid_getvar in outbound socket but the originate command it self is issued in inbound socket. 

appreciate any insights.
