Chapter 17: Hotline service
The Hotline service allows you to provision a SIP IP Deskphone to a Hotline Phone. From a Hotline
Phone, you can automatically make a call to a designated number.
A Hotline Phone is a dedicated IP Deskphone that has only one target. You cannot make a call to
any other destinations; even emergency calls, such as E911 are not permitted. A Hotline Phone
does not know the Hotline target and relies on the server to replace the To field of all INVITE
messages sent from the Hotline Phone with the Hotline target to complete the call.
Important:
You cannot place calls if the server is unavailable during an upgrade.
Making a Hotline call
A call to a Hotline target is automatically placed when an off-hook condition occurs, or when you
press digits during idle on-hook, and then lift the handset.
Hotline Service allows only one hotline user to login to the Hotline Phone. The Multi-user Login
feature is restricted to one user only.
Hotline service restrictions
Because the Hotline Phone is a dedicated IP Deskphone used only for Hotline service, certain
features are restricted on the Hotline Phone.
The following is a list of features, on the IP Deskphone, that are restricted on the Hotline Phone.
• Call Transfer
