It is capable of sending multiple one-way RTP streams to devices such as Cisco IP phones or gateways, and it uses SCCP messages to establish the RTP stream. The device must be capable of SCCP to utilize this feature. Tones and announcements are predefined by the system. The announcements support localization and also may be customized by replacing the appropriate .wav file. The annunciator is capable of supporting G.711 a-law and mu-law, G.729, and Wideband codecs without any transcoding resources. The following features require an annunciator resource: •Cisco Multilevel Precedence Preemption (MLPP) This feature has streaming messages that it plays in response to the following call failure conditions. –Unable to preempt due to an existing higher-precedence call. –A precedence access limitation was reached. –The attempted precedence level was unauthorized. –The called number is not equipped for preemption or call waiting. •Integration via SIP trunk SIP endpoints have the ability to generate and send tones in-band in the RTP stream. Because SCCP devices do not have this ability, an annunciator is used in conjunction with an MTP to generate or accept DTMF tones when integrating with a SIP endpoint. The following types of tones are supported: –Call progress tones (busy, alerting, and ringback) –DTMF tones •Cisco IOS gateways and intercluster trunks These devices require support for call progress tone (ringback tone). •System messages During the following call failure conditions, the system plays a streaming message to the end user: –A dialed number that the system cannot recognize –A call that is not routed due to a service disruption –A number that is busy and not configured for preemption or call waiting •Conferencing During a conference call, the system plays a barge-in tone to announce that a participant has joined or left the bridge. An annunciator is automatically created in the system when the Cisco IP Voice Media Streaming Application is activated on a server. If the Media Streaming Application is deactivated, then the annunciator is also deleted. A single annunciator instance can service the entire Unified CM cluster if it meets the performance requirements (see Annunciator Performance<http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/7x/media.html#wp1046582>); otherwise, you must configure additional annunciators for the cluster. Additional annunciators can be added by activating the Cisco IP Voice Media Streaming Application on other servers within the cluster. The annunciator registers with a single Unified CM at a time, as defined by its device pool. It will automatically fail over to a secondary Unified CM if a secondary is configured for the device pool. Any announcement that is playing at the time of an outage will not be maintained. An annunciator is considered a media device, and it can be included in media resource groups (MRGs) to control which annunciator is selected for use by phones and gateways. Annunciator Performance By default, the annunciator is configured to support 48 simultaneous streams, which is the maximum recommended for an annunciator running on the same server (co-resident) with the Unified CM service. If the server has only 10 Mbps connectivity, lower the setting to 24 simultaneous streams. A standalone server without the Cisco CallManager Service can support up to 255 simultaneous announcement streams, and a high-performance server with dual CPUs and a high-performance disk system can support up to 400 streams. You can add multiple standalone servers to support the required number of streams. On Sat, Apr 27, 2013 at 11:55 AM, William Bell <b...@ucguerrilla.com> wrote: > That is not accurate.
