Parallel forking means to send an incoming INVITE to multiple SIP destinations in the same time - how / where the destinations are fetched from , it is not relevant.

Hi Bogdan-Andrei,

Thanks for your reply. As I know parallel forking works when same user registered with multiple devices. In this scenario we have multiple users instead of same user. Does parallel forking works for multiple users? I want to implement simple PTT scenario.

Ali

    Hi Ali,

    That is called SIP parallel forking and you can do it by using the
    append_branch() function [1] or $branch variable [2] in order to
    add multiple destinations for an INVITE.

    Hi all,

    Is it possible to send multiple initial request to multiple
    destinations? something like b2bua but with multiple destinations.

    I draw the diagram in this gist:
