Q.850;cause=3 - outgoing calls fail with some ISP

Hello to everybody,

 

I have an issue with a CUBE [Cisco 2901- IOS 15.5(1)T2], the system (CUCM 11 and CUBE) works fine using an internet link to ISP "A"but when the CUBE uses another ISP "B" the system is unable to make outgoing calls (direct to PSTN) but can manage well incoming calls. 

 

During debugging I see the CUBE stopping work at 100 Trying message, after this appears a "SIP 404 Not Found" message with Q.850=cause 3 (no route to destination).

 

What may be the problem?

 

I can add that the ISP "B" has not a constant throughput, I mean if I try doing upstream udp traffic I see a systematic holes each two seconds (see the image "upstream.jpg")

Below the debugging:
