Adding and Editing Telephony Sharing Information

When you add or edit telephony sharing information, you specify the names of the secondary facilities that are using the principal facility's shared telephony service. You also optionally specify the access numbers used by the secondary facilities.

1. Navigate to the Telephony-Sharing section in the Add/Edit Facility page.
2. Click the Add button to display the Add Shared Telephony Info dialog box.
3. Enter or edit the following information:

   Field	Description
   Facility	Specify a secondary facility that will use the shared telephony service of the principal facility. Important: You cannot select a principal facility with telephony enabled. If you select a principal facility with telephony enabled, the system automatically disables telephony for that facility.
   Guest Access Number	(Optional) Specify the area code and phone number of a DID line or guess access for this facility. This number is for guest access to the Vocera system. When callers dial the Guest Access Number, they are allowed to place a call but are not identified to the called person. Because guest users are not authenticated, they can call other users but they cannot issue voice commands. If you want the secondary facility to have the same Guest Access number as the primary facility, leave this field blank or enter the primary facility's Guest Access number. If you want the secondary facility to have a different Guest Access number, coordinate with your PBX administrator, then enter the number.
   Direct Access Number	Optionally specify the area code and phone number of a DID line for this facility. This number is for specially licensed user access to the Vocera system. This field is used only if your Vocera system has a digital or IP connection to the PBX, you have selected ISDN or SIP signaling protocol, and Calling and Called Party Information is enabled on the PBX. Vocera uses the Caller ID feature to automatically authenticate users when they call the Direct Access number from their desk phone or cell phone.
   Tie Line Prefix	Specify the prefix of the dial string used to place calls through the tie line to the selected facility that is sharing the principal's telephony service. Alternatively, this field could also be used to specify a prefix for Direct Inward Dialing (DID) numbers at the selected facility. For tie lines, enter the tie prefix plus the tie line. For example, if the tie prefix is 8 and the tie line is 257, enter 8-257. For DID numbers, identify the DID prefix by determining the constant digits that become the prefix to an extension to produce a full DID number. For example, if the format of your DID numbers is 408-882-nnnn, the DID prefix is 408-882. In the US locale, the full DID number must be a 10-digit telephone number that includes the area code. In other locales, full DID numbers include city and region codes. The Vocera Platform prepends the Tie Line Prefix to the extension dialed to generate the complete dial string for the selected facility. If the selected facility does not have its own PBX and a tie line or DID numbers, leave this field blank. Note: The Tie Line Prefix is used for all extensions dialed for the selected facility. Only one Tie Line Prefix can be used per shared facility.

4. Click Done to add this facility to the list and close the dialog box.
