What if all lines are busy?

Hello,

I’m using “.call” approach for making outgoing calls. If the person who is supposed to receive the call doesn’t answer it, Asterisk is able to retry calling the same person (As per the Retry count specified in the .call file).
I configured the retry limit as 3.

Say that I have 4 outgoing lines from my office. What will Asterisk do if Asterisk server tries to make a call when all the 4 outgoing lines are already in use? Will Asterisk treat it as one attempt?
Meaning: Out of 3 retries, will I be left out with only 2 now?

I’m asking this question as I cannot test this scenario. Currently I’m using softphones for my development and eventually I will be connecting asterisk to my existing phone network.

Thanks!
