Wrong "outisbusy" message on some phone numbers

I have a working FreePBX install. We are calling about 200 phone numbers each day without any problem. However I encounter a problem with some numbers that are reporting “outisbusy”. I can NEVER call those specific numbers. That call does not even reach our SIP provider. It is blocked in the PBX. I can normally call that number with my cellphone. So it is NOT busy. No numbers are blacklisted. Even if I specify this specific number in my DIALPATTERN list I am unable to call it. Again, the call attempt never shows up in my SIP providers log.

Please post a call trace with PJSIP logging enabled via pastebin.

You were asked to provided the PJSIP logging. You didin’t. If I understand the log correctly, the call to the provider was attempted, so the PJSIP logging is essential. You need to issue the “pjsip set logger on” command, in the same session, before making the call.

Cause code 38 is Network Out of Order.

Thank you all for your time. Problem was boiled down to a problem with certain numbers at our SIP provider. It is solved now.
