Configuring Additional Call Features
This chapter describe how to configure three-party G.711 ad hoc conferencing and music on hold (MOH) for Cisco Survivable Remote Site Telephony (SRST).

Information About Configuring Additional Call Features
Optional features available for configuration include three-party G.711 ad hoc conferencing and MOH. MOH is available from flash files on the Cisco SRST router and for G.711, on-net VoIP, and PSTN calls.
For information on configuring MOH from a live feed, see the Configuring SRST MOH Live-Feed Support section at http://www.cisco.com/univercd/cc/td/doc/product/access/ip_ph/srs/srsinter/moh.htm.
Also available is an eXtensible Markup Language (XML) application program interface (API). This interface supplies data from Cisco SRST to management software.
How to Configure Additional Call Features
This section contains the following tasks:
• Enabling Three-Party G.711 Ad Hoc Conferencing (Optional)
• Configuring MOH for G.711 VoIP and PSTN Calls (Optional)
• Configuring MOH from Flash Files (Optional)
• Defining XML API Schema (Optional)
Enabling Three-Party G.711 Ad Hoc Conferencing
Enabling three-party G.711 ad hoc conferencing involves configuring the maximum number of simultaneous three-party conferences supported by the Cisco SRST router. For conferencing to be available, an IP phone must have a minimum of two lines connected to one or more buttons. See the "Configuring a Secondary Dial Tone" section on page 50.
SUMMARY STEPS
1. call-manager-fallback
2. max-conferences max-conference-numbers
3. exit
DETAILED STEPS
Examples
The following example configures up to eight simultaneous three-way conferences on a router.
call-manager-fallback
max-conferences 8
Configuring MOH for G.711 VoIP and PSTN Calls
MOH configuration works with G.711 VoIP and PSTN calls only. For all other calls, such as internal calls between Cisco IP phones, a tone is heard. The MOH file can be in .wav or .au file format. However, the file format must contain 8-bit 8-kHz data, such as a-law or u-law data format.
The moh command allows you to specify the .au and .wav format music files that are played to callers who have been put on hold.
Prerequisites
You can obtain .au files from the Technical Support Software Download site at http://www.cisco.com/cgi-bin/tablebuild.pl/ip-iostsp. Copy the music-on-hold.au file to the flash memory on your Cisco SRST router.
SUMMARY STEPS
1. call-manager-fallback
2. moh filename
3. exit
DETAILED STEPS
Example
The following example enables the playing of an audio file called classical.au on G.711, on-net VoIP, and PSTN calls:
call-manager-fallback
moh classical.au
Configuring MOH from Flash Files
The MOH Multicast from Flash Files feature facilitates the continuous multicast of MOH audio feed from files in the flash memories of Cisco SRST branch office routers during Cisco CallManager fallback and normal Cisco CallManager service. Multicasting MOH from individual branch routers saves WAN bandwidth by eliminating the need to stream MOH audio from central offices to remote branches.
Configuration for this feature involves configuring Cisco SRST and Cisco CallManager to work together, which is described in Integrating Cisco CallManager and Cisco SRST to Use Cisco SRST As a Multicast MOH Resource at http://www.cisco.com/univercd/cc/td/doc/product/access/ip_ph/srs/srsinter/moh.htm.
The MOH Multicast from Flash Files feature can act as a backup mechanism to the MOH live feed feature. MOH live feed provides live feed MOH streams from an audio device connected to an E&M or FXO port to Cisco IP phones in SRST mode. Music from a live feed is from a fixed source and is continuously fed into the MOH playout buffer instead of being read from a flash file. See the Configuring SRST MOH Live-Feed Support section at http://www.cisco.com/univercd/cc/td/doc/product/access/ip_ph/srs/srsinter/moh.htm.
Defining XML API Schema
The Cisco IOS commands in this section allow you to specify parameters associated with the XML API. For more information, refer to the XML Developer Guide for Cisco CME/SRST.
SUMMARY STEPS
1. call-manager-fallback
2. xmlschema schema-url
3. exit
DETAILED STEPS
Where to Go Next
If you need to configure security, see the " Setting Up Secure SRST" chapter, or if you need to configure voicemail, see the " Integrating Voice Mail with Cisco SRST" chapter. If you do not need any of those features, go to the "Monitoring and Maintaining Cisco SRST" chapter.
