Hi,
the idea is to do parallel forking (not wait for reply or timeout), but wait (for each branch) a specific amount of seconds, before sending out the INVITE request to the contact.
This could be useful, if a user
- has a mailbox <somewhere>, which answers the call without waiting
(like many cell phone providers' mailboxes do, if a call gets forwarded to them)
- would like to predefine multiple destinations, for example tel.
exchange and users phone, but the users phone should only ring _additionally_ , if the call was not answered for <x> seconds by the tel. exchange.
- ...
there are many use cases, but a function would be needed, which delays further script processing for specific branches only or (that could be the better solution) the definition of a special branch-individual avp which holds the seconds to wait and which is evaluated by tm.

Hello
Have you checked TM's t_suspend() and t_continue() [1]? ATM, they are only usable internally from modules, but I think they can provide the building blocks for what you want.

Hi,
What is the goal of a "delayed branch"? What you can do (and could do for many versions now) is the serial forking together with a defined timeout of some seconds for each branch... (e.g. first try location 1 for a few seconds, then try location 2 for few seconds, ...).
