ECTION
Due to the nature of analog-to-digital conversion, considerable echo may be
encountered when using Analog Trunks with IP Phones.
Due to all Analog trunks being different, padding of the Analog Trunks in PRG 81-07
and 14-01 may be necessary. Even after the pad changes are made, echo may still
be present the first few seconds of the call while the echo cancellers are learning the
characteristics of the circuit on this call.
It is recommended to use digital trunks when using IP phones for best performance.
Digital (ISDN, T-1, and SIP) trunks do not suffer from this problem.
When analog trunks are installed in an SL1100, PRG 90-68 (Side Tone Auto Setup)
must be used. This program will automatically change the setting of 81-07 after
multiple tests are performed on the analog line. During these tests the system will not
be usable, and the system must be reset once the test are finished.
Anytime new analog trunks are added to the system, PRG 90-68 MUST be used.

ECTION
A new version of NEC firmware for the IP Phones can be applied automatically or
manually.
The upgrade requires using an FTP/TFTP server. This is a software package that
runs on a PC. (These can be downloaded from the Internet, usually as freeware or
shareware.)

Manually Upgrading Firmware

Manually upgrading the firmware uses an FTP/TFTP server, but requires the
engineer visit each IP Phone individually. This may take longer, but is more
controlled as the downloads can be staggered to avoid excessive bandwidth
utilization.
To manually upgrade the firmware:
1. Install and configure an FTP/TFTP server.
