I know this is an old thread but I have almost exactly the same problem. I think I better try here to see if I can get help from here instead of starting a new topic.
I just got my obi110 today. I had set up the GV service (SP1) and a sip service through supervoip (SP2). The latter one is mainly for calls to China. Thus, I would like to route all calls start with 01186 with 10 or 11 x's to SP2. I can make 01186 calls if I dial **2 before dialing the 01186x. number. Following RonR's posting, I modified the SP1 digimap by adding the first entry as (**201186xxxxxxxxxx|.....). However, it doesn't seems to work. It waited for some time and then sent the busy signal. Can RonR or anybody else point out what I did wrong or give me some suggestions?
Also, can someone tell me where to check the log in obi110?
Thanks in advance.
