Troubleshooting
To verify the TSP is functioning after completing the The innovaphone PBX V8 (Winxx. Release) TAPI Service Provider configuration dialog (as described in TSP Installation steps 13 through 17), click the Verify button. If the TSPUI dialog displays a "Master PBX not accessible" message, then a problem exists… If you can ping the PBX at the IP address entered in the PBX\Master field, then most likely the Account, Password, or Username string was misspelled. Another possibility is that the TAPI User has no Rights assigned; see Configure TAPI User step 13.
