![]() ![]() Ring starts and ends at the zero crossing. Number of samples in the ring is evenly divisible by 240. The PCM files for the rings must meet the following requirements for proper playback on Cisco IP phones: ![]() PCM File Requirements for Custom Ring Types The RingList.xml file can include up to 50 ring types. The following sample shows a RingList.xml file that defines two phone ring types:ĭisplayName and FileName are required for each phone ring type. The DisplayName and FileName fields must not exceed 25 characters. The following characteristics apply to the definition names:ĭisplayName defines the name of the custom ring for the associated PCM file that will display on the Ring Type menu of the Cisco IP phone.įileName specifies the name of the PCM file for the custom ring to associate with DisplayName. The CiscoIPPhoneRingList XML object uses the following simple tag set to describe the information: The C:\ Program Files\Cisco\TFTPPath directory of the Cisco TFTP server for each Cisco CallManager contains this file. Each ring type contains a pointer to the PCM file used for that ring type and the text that will display on the Ring Type menu on a Cisco IP phone for that ring. The RingList.xml file defines an XML object that contains a list of phone ring types. Step 4 Place the new PCM files you created in the C:\ Program Files\Cisco\TFTPPath directory on the Cisco TFTP server for each Cisco CallManager in your cluster. Step 3 Save your modifications and close the RingList.xml file. See the "RingList.xml File Format" section for information about how to format this file, along with a sample RingList.xml file. ![]() Step 2 Use an ASCII editor to edit the RingList.xml file. Ensure the PCM files comply with the format guidelines listed in the "PCM File Requirements for Custom Ring Types" section. Step 1 Create a PCM file for each custom ring (one ring per file). The following procedure only applies to creating custom phone rings for the Cisco IP Phone 79 models. This appendix describes how you can customize the phone ring types available at your site by creating your own PCM files and editing the RingList.xml file. The PCM files, along with an XML file (named RingList.xml) that describes the ring list options available at your site reside in the TFTP directory on each Cisco CallManager server. Cisco CallManager also provides a default set of additional phone ring sounds that are implemented in software as pulse code modulation (PCM) files. Cisco IP phones ship with two default ring types that are implemented in hardware: Chirp1 and Chirp2. ![]()
