* does not try next trunk in list

Hi, people!
There are several SIP trunks connecting * to my SIP provider softswitch (Mera if it does matter). Each trunk has its loginname equal to phone number (for example 2110012). When somebody calls out using the first trunk in list, nobody else can call out anymore, receiving a busy tone. Here are the log of the call:

It displays that * does make no attempts to use another trunk.
Some of my russian friends explained me that " 603 “Out of capacity” message is interpreted by * as if the person called is busy and that is why making another trial according to a human logic does not make sense.
Any help would be appreciated. Thank u.

Asterisk doesn’t hunt for free SIP “trunks”. This is done by dialplan code. Typically this is supplied as part of a GUI, but could have been written specially for you. You need to take this up with whoever wrote that dialplan code.

There will be part of that code that tries to decide which failures will mean the call will fail via any trunk and which will fail by a particular trunk.

Ok, gotcha. Thank u very much. I really use freepbx as a GUI.
