Loss connect between 2 PBX

Hi everyone,

I created call file from pbx(A) and send it to pbx(B) to callout. The problem is when I send 50 call files at the same time, everything is ok.
But, try it with 200 call files at the same time. pbx(B) received only ~120-150 calls.

pbx(A) call log response:

Dont know why, please help :smiling_face_with_tear:

Please explain the picture. It appears to show FreePBX trying to start seven calls, but the external system only starting to accept six of them, It doesn’t show 120+ calls.

What happens to the call files of the calls that weren’t accepted.

How many calls does the service provider guarantee to handle in a fast burst? I don’t think anyone would design a service for such usage; I 'd expect them to design for a maximum number of normal duration calls, in progress, with start times random.
