[OpenSIPS-Users] R: Ring Group - Memory Hunt - with serial forking?

[Mauro Davi']

Sorry Bogdan,

If I understand, this is the scenarious that I implemented.

With the lookup function patch (that add the q value to the input parameter, the same assigned to you) Chris can invoke the lookup function three time with the three subscriber and obviously three different qvalue. After he can invoke the serialize_branches(1) function.
Finally he can use the next_branch route in the failure route block to fork sequentially the INVITE on the next subscriber...
And when the next_branch function return "no other branches" he can forward the call to the voicemail...

I don't know if the patch is applied but in this way, I think, that Chris can solve his problem...

Regards,
	MD

This is something you cannot do right now - to wait N seconds and create 
another branch of an existing call (without cancelling the previous 
branches).

What you want to do is a kind of "asynchronous" parallel forking.

Bogdan
