Pre requisite:
Asterisk 13.8.0
User-1 is registered using 2121212121.

Scenario:

User-1 calls User-2
User-2 Answers the call
User-2 presses *0
User-1 is redirected to Conference room 1
User-2 gets hanged up

Expected:
5. User-2 should be redirected to Conference room 1

Why is SIP/1120 getting hanged up?

Post your confbridge.conf file.

I would note that the use of macros and subroutines is unsupported in features.conf, even though it seems to work most of the time, and this also seems to be doing pbx state modifications on other channels in the same call, so I’m not too surprised that it doesn’t work.

But features.conf says

; IMPORTANT NOTE: The applicationmap is not intended to be used for all Asterisk
;   applications. When applications are used in extensions.conf, they are executed
;   by the PBX core. In this case, these applications are executed outside of the
;   PBX core, so it does *not* make sense to use any application which has any
;   concept of dialplan flow. Examples of this would be things like Goto,
;   Background, WaitExten, and many more.  The exceptions to this are Gosub and
;   Macro routines which must complete for the call to continue.

The exceptions to this are Gosub and Macro routines which must complete for the call to continue.

If not Gosub or Macro then how can I achieve redirecting an user to conference bridge?
