The only reason you (or your alarm dialer) would use **1 to dial a number is if SP1 is
not your PrimaryLine. If SP1
is your PrimaryLine and you want calls to use SP1, then no **1 is needed.
If your PrimaryLine is not SP1 and you want calls to use SP1, then it is necessary to use **1.
To make the change I suggested, you can either use the OBiTALK Web Portal OBi Expert which documented in this post:
OBi Expert Configuration (Introduction)or you can make the changes directly to the OBi by logging into the IP address returned by dialing ***1.
If you make the changes directly, you must also set the following:
System Management -> Auto Provisioning -> ITSP Provisioning -> Method : Disabled
System Management -> Auto Provisioning -> OBiTALK Provisioning -> Method : Disabled
