[Freeswitch-users] Lua - origination to local endpoint then bridge to either local or remote destination: no audio

[Alex Crow]

Hi all,

I have a Lua script that I am calling from XML RPC from a browser (also 
same behaviour from the console). The script originates a session to one 
extension, when that is picked up it originates another session to 
another endpoint and then bridges the two sessions.

The issue is that if the first freeswitch.Session(<endpoint>) has the 
endpoint local to the FS box, there is no audio at all after the bridge 
is executed. If the first session is a remote endpoint, it works OK 
apart from the fact that that endpoint does not hear ringing, but when 
the second session is answered all is well. If both endpoints are 
remote, everything is perfect.

Here is my Lua script - the no-audio version:

local calling_user = argv[1];
local called_num = argv[2];

local session1 = freeswitch.Session("user/"..calling_user);

session1:sleep(500);

session1:answer();

if (session1:ready() == true) then
         local session2 = 
freeswitch.Session("[origination_caller_id_number=02023493482]sofia/gateway/10.10.0.2/" 
.. called_num);
         session2:answer();

         if (session2:ready() == true) then
                 freeswitch.consoleLog("INFO","Bridging\n");
                 freeswitch.bridge(session1, session2);
         end

end

This one works fine:

local calling_user = argv[1];
local called_num = argv[2];


local session1 = 
freeswitch.Session("[origination_caller_id_name="..called_num.."]sofia/gateway/10.10.0.2/" 
.. calling_user);

session1:answer();

if (session1:ready() == true) then
         local session2 = 
freeswitch.Session("[origination_caller_id_number=02076084900]sofia/gateway/10.10.0.2/" 
.. called_num);
         --either the above or the below both work in this script, 
except the below does not present ringing to session1
         --local session2 = 
freeswitch.Session("[ringback=%(400,200,400,450);%(400,2200,400,450)]user/" 
.. called_num);
         session2:answer();

         if (session2:ready() == true) then
                 freeswitch.consoleLog("INFO","Bridging\n");
                 freeswitch.bridge(session1, session2);
         end

end

Where gateway 10.10.0.2 is a Mitel 3300 connected to the PSTN via ISDN30.

I can provide logs if required - please advise as this is driving me 
bonkers!
