When you configure two or more facilities to share a telephony service, enable telephony for one facility only. The facility for which telephony is enabled is considered the principal facility. Facilities that use the shared telephony service of a principal facility are called secondary facilities.
Do not enable telephony for secondary facilities that use the telephony service of a principal facility. Instead, use the Telephony- Sharing section to configure the principal facility to share the telephony service with the other facilities.
On the principal facility's Telephony-Sharing section, click Add to display the Add Shared Telephony Info dialog box. Specify the name of the facility that is sharing the principal's telephony service, then do one of the following:
If the facilities have the same access numbers:
Leave the Guest Access Number, Direct Access Number, and Tie Line Prefix fields blank.
This configuration specifies that Vocera will search the combined grammars of the principal and sharing facility when incoming callers respond to the Genie.
If the facilities have different access numbers:
If using Vocera SIP Telephony Gateway for telephony integration, enter values in the Guest Access Number and Direct Access Number fields. Leave the Tie Line Prefix fields blank.
This configuration specifies that Vocera searches only the grammars for a facility as specified by the access numbers or line numbers when incoming callers respond to the Genie.
