Linksys SPA9000 manual IP Telephony System

IP Telephony System

The default is (<L1,2,3,4>9xx.); this indicates that any of the four lines can be used for any target number starting with 9. For example, with this dial plan, the caller dials 9 before entering the external phone number.

Internal Music URL. Enter the Uniform Resource Locator (URL), also known as a web address, to download a music file for the music-on-hold and call park features. This is its format: [tftp://]server_IP_address[:port]/path. TFTP is the only protocol supported for music download. The default port is 69. Saving a new URL will reboot the System. After its reboot, the System will download the file and store the samples in flash memory.

The music samples are encoded in G711u format at 8000 samples/second. This file should not contain any extra header information, and its maximum length is 65.536 seconds (524,288 bytes). For more information, refer to “Appendix D: New Music for the Music-on-Hold Feature.”

Internal Music Script. This script tells the System how to play the downloaded music file. This is its format: [section[,(section[,...]]]

Each section should be in this format: [n (start/end[/pause])] [pause2]

The variable n is the number of times you want a section to repeat before moving to the next section.

The start/end is the starting and 1+ending sample for the section. Note that the samples are numbered from 0 to total-length - 1. You may enter -1 or a very large number if the end of the file should be the ending sample. The default start value is 0, and the default end value is the end of the file.

The variable pause is the number of samples to pause after the ending sample has been played. The default is 0.

The variable pause2 is the additional number of samples to pause after the entire n repetitions of the section have been played. The default is 0.

A maximum of 16 sections can be specified. Samples should be encoded in G711u format at

8000 samples/second. After all sections are played, they are replayed, starting with the first section.

For example, the default Internal Music Script setting is 2(0/230954),2(230954/444720),(0/230954)40000. The first section is 2(0/230954); samples 0 through 230954 will be played twice. The second section is 2(230954/444720); samples 230954 through 444720 will be played twice. The third section is (0/230954); samples 0 through 230954 will be played once.

The last section is 40000. The ending pause will last for 40,000 samples. Each sample lasts 1/8000 of a second, so 40,000 samples equals 5 seconds. When this pause is over, the sections are replayed.

Internal MOH Refresh Intvl. The System can refresh an internal music session periodically. The default is 0, which disables the refresh function.
