[asterisk-dev] qeustion about app_dial.c do_forward function getting the forwarding peer

[Stefan Schmidt]

Hello klaus,

thanks for the link to this issue, this was the patch i was thinking of,
my problem is that when i use your patch:
pbx_builtin_setvar_helper(o->chan, "FORWARDER", winner->name);
after inherit the orig and the winner channel, i just got the Local
channel 1 in this Var. What i need was the name of the redirecting channel.

in 1.6 the app_dial looks diferent to 1.4 so there is the incoming orig
chan (in) the winner which is first c = o->chan which is the channel
which starts the forward (with the peer i need) but is set to the new
outgoing channel after
c = o->chan = ast_request(tech, in->nativeformats, stuff, &cause); (row:
533)

what i have done to make it useable for me is a
pbx_builtin_setvar_helper(in,"FORWARDING_PEER",c->name);
before this row, so i really have the channel name of the peer which
starts the forward, but set it to the orig incoming channel (in).

so i have to use
pbx_builtin_getvar_helper(chan->chan_list.next->chan_list.next,"FORWARDING_PEER")
to get the channel name which starts the forward.

i still dont know why there are 2 local channels when doing a forward,
but i think that the first local points to the incoming and the second
local channel starts the outgoing channel and when this is successfull
the orig and the outgoing is bridged and the local channels are stopped.

maybe you shout think about this when doing this patch.

best regards

steve
