I have an OBI110 configure:
sp1: google voice
sp2: freephone line
gateway3:
voip.msit used to be working, when I tried dial **3011xxxx, or 011xxxxx (it should be automatically routed to gateway 3 via sp2).
now
- when I am using **3011xxxx, it always goes to sp1 NOT sp2.
- if I directly dial 011xxxx, both sp1 or sp2 are dialing when I monitor the status, for sure sp1 cannot which showing trying.
I awlays heard :"the number you are dialing 011xxx was rejected by service provider becuase 503".
can anyone tell me why? it was working before, I didnot change anything.
