[OpenSER-Users] "always" serial fork with LCR?

[Amit Sharma]

Hi Bogdan,
   Your understanding of the requirement is absolutely correct.

    So what I understand from your reply is that this should be achievable
with the functionality already available in core. Is that correct?

    Thanks again for a prompt reply. I will focus on the functionality in
core to implement the desired behavior.

Regards,
Amit
