I did not touch the "DigitMap" field in the Voice Gateway page. I leave it as default, like:
DigitMap = (xx.)
What I mean is that, according to the manual, the basic way to config a voice gateay is like:
AccessNumber: SP1(toronto.voip.ms)
AuthUserID: My_voip.ms_user_name
AuthPassword: My_voip.ms_password
But according to that URL from my post above, there is a new way to config a voice gateay, like:
AccessNumber: SP1(toronto.voip.ms;ui=My_voip.ms_user_name:My_voip.ms_password)
AuthUserID: ( Leave empty )
AuthPassword: ( Leave empty )
But I found this new way is not working. If proxy server address is too long, or if the user name is too long, or if the password is too long, or if the phone number dialed is too long, etc, the call will fail, because OBI-100 will do some strange truncation in such situation.
