[Freeswitch-users] Failed to get callee number during the call

[fieldpeak]

Hello Friends,

i would like to get the callee number during the call, i used the
function 'switch_channel_get_variable',
however, when i display it to the console, it shows 'null', i tried
call this func before and after answering the call, both failed, could
anyone help advise if i used the correct function or how to realzize
it, thanks.

source code as below,

	const char* in_calledstation;

	in_calledstation = switch_channel_get_variable(channel,
"sip_callee_id_number");
	
	switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_INFO, "in_username:
%s, in_calledstation: %s, in_uniqueid: %s, sessiontime: %d \n",
in_username, in_calledstation, in_uniqueid, sessiontime);
