It is looking for the 331NUMNOFOUND in context named "default".
Do you have this context? Does the extension exists in the context?

Do you have a register line in your sip.conf for this external provider? 
In the register line you can specify the extensions/device to use in the 
sip.conf so it knows the right context to start in extensions.conf 
instead of the default context.

For example: register => username:password at sip.voipbuster.com/Trunk-Telco
