Re: [asterisk-dev] Detecting B-leg channels

The thing is, when attended transfer happens, Asterisk connects previously unrelated channels without going to the dialplan. I keep a number of variables which help me track call state on both channels, and their values become obsolete on attended transfer, as channels are now in a completely n

Re: [asterisk-dev] Detecting B-leg channels

Yes, I suspected as much. I've seen that app_dial keeps a list of outbound channels, but doesn't store it anywhere. So that's a dead end, pretty much. On 24. 08. 2021. 20:45, George Joseph wrote: On Tue, Aug 24, 2021 at 12:20 PM Nikša Baldun > wrote: I have c

Re: [asterisk-dev] Detecting B-leg channels

I have checked it, and that led me to bridge.c. Perhaps I wasn't clear enough. These are the channels involved in attended transfer: (transferee) <> (transferer1) (transferer2) <> (transfer target) Transferee and transfer target are not readily available in res_pjsip_refer.c, but I can get the

Re: [asterisk-dev] Detecting B-leg channels

What's the overall scenario you are trying to solve? Perhaps there is another way to do what you want to do without even modifying Asterisk code? For example, maybe this is something an ARI application could handle, or even straight dialplan using a combination of app_dial, pre-dial handlers, and s
