Voice-system
The Auto Attendant on Cisco Unified Communications 500 offers holiday and business schedules to enable time-
features
of-the-day routing of incoming calls.
Voice-system
A secondary dial tone is available for Cisco Unified IP Phones connected to Cisco Unified Communications 500 in
features
the PBX mode. The secondary dial tone is generated when you dial a predefined PSTN access prefix and
terminates when you dial additional digits.
Voice-system
The SSL Phone Client on the SPA525G IP phone provides secure connectivity to a UC500 or SR500 series over
features
the internet. The SSL Phone Client at the remote site does not need a teleworker router, making it an ideal
solution for simple scenarios that require voice-only connectivity.
Voice-system
The sequencing method of hunting always starts with the first member of the hunt group and hunts through all the
features
members in the sequential order.
Voice-system
SIP is a signaling protocol widely used for controlling multimedia communication sessions such as voice and
features
video calls over IP. Cisco Unified Communications 500 supports Cisco SIP endpoint devices as well as SIP trunks
to SIP providers.
Voice-system
SIP dial plans enable call routing using the SIP protocol. The dial plans route calls toward a SIP server, which
features
could be either another Cisco Unified Communications 500 at a remote site or a SIP server hosted by a SIP
provider.
A dial plan is a set of dial patterns that SIP phones use to determine when digit collection is complete after you go
off-hook and dial a destination number. Dial plans allow SIP phones to perform local digit collection and recognize
dial patterns as your input is collected. After a pattern is recognized, the SIP phone sends an INVITE message to
the Cisco Unified Communications 500 to initiate the call to the number matching your input. All of the digits you
entered are presented as a block to the Cisco Unified Communications 500 for processing. Because digit
collection is done by the phone, dial plans reduce signaling messages overhead compared to Keypad Markup
Language (KPML) digit collection.
SIP dial plans eliminate the need for you to press the Dial softkey or # key, or to wait for the interdigit timeout to
trigger an outgoing INVITE. You can configure a SIP dial plan and associate the dial plan with a SIP phone. The
dial plan is downloaded to the phone in the configuration file.
Users,
IP phones can communicate using several protocols, including H.323, SIP, and Media Gateway Control Protocol
phones, and
(MGCP). SIP IP phones use the SIP protocol to communicate with a SIP server.

Voice-system
SIP trunks provide an alternative to the traditional PSTN (digital and analog) connectivity options. SIP trunks are
features
provisioned through SIP service providers that provide PSTN connectivity.
Voice-system
The SIP call transfer and call forwarding supplementary services feature introduces the ability of SIP gateways to
features
initiate blind, or attended, call transfers by passing the call control back to the originating devices. Disabling these
supplementary services forces the SIP gateway to handle these call conditions locally.
Users,
A shared directory number allows the same number to appear on two different IP phones. A call made to a shared
phones, and
directory number rings all the IP phones that have a button assigned to the shared number. A call made from the
extensions
shared directory number ties up the shared-dn-buttons on the rest of the IP phones. If a call on the shared
directory number is put on hold, any of the IP phones can resume the on-hold call.
Users,
The overlay feature allows a single IP phone button to be associated with multiple directory numbers. A call to any
phones, and
of the associated directory numbers rings the IP phone on the overlaid button. Shared directory numbers can also
extensions
be part of the overlay configuration. Primary extensions cannot be part of the shared overlay ephone-dns.
Voice-system
The basic Auto Attendant is included in the Cisco Unified Communications 500 as aa_simple.aef script. It
features
supports dial-by-extension, alternate, holiday, and business-hours greetings.
Voice-system
SNR allows you to have incoming calls to a single number simultaneously ring an IP phone and a remote
features
destination such as a home or mobile phone. You can answer incoming calls to your SNR number on your IP
phone or at your remote destination and pick up in-progress calls on your desktop phone or the remote
destination without losing the connection.
If you do not answer the call within 5 seconds, the Cisco Unified Communications 500 system rings the remote
number while continuing to ring your IP phone extension. If you answer the call on your IP phone, you can send
the call to the remote phone by pressing the Mobility softkey.
If you answer the call on your remote phone, you can pull back the call to the IP phone by pressing the Resume
softkey. You can also change the SNR remote destination using the IP Phone menu.
Users,
Softkeys are keys that appear on the bottom of the IP phone LCD. They allow you to access various features such
phones, and
as call forward, call transfer, conferencing, and call park. The softkeys available for use change dynamically
extensions
according to whether the phone is in connected, ringing, idle, or seized (handset is lifted). Additional softkeys are
also automatically enabled when advanced features, such as SNR and live record, are enabled.
Voice-system
Software conferencing is the type of voice conferencing that is supported by default on the Cisco Unified
features
Communications 500. It does not require any hardware resources; the audio mixing is done within the application
software. Software conferencing allows a maximum of three parties in a conference, with maximum of eight
simultaneous conferences.
