For a windows tftp server, download 3cdv2r10.zip from
support.3com.com/software/utilit … 32_bit.htm
Or download the avaya tftp server also available where you get the firmware updates.
Download the latest firmware updates and documentation for the 4621sw phones from
support.avaya.com/css/appmanager … 2754378092
(46xxH323_030909.zip and 46xxSIP_upgrade_030909.zip is what I downloaded)
Download 46xxsettings.txt from support.avaya.com/css/appmanager … 0372125345
You may need to modify the 46xxsettings.txt for your enviorment.
Then, using the tftp software, setup the tftp download directory and extract the zip files into it. If you are using static ip addressing on your phones, set the “FileSv” entry to the ip address of the tftp server and reboot the phone.
I don’t know anything about a gxe grandstream. If it’s a sip voip phone, then yes it should work just fine with asterisk 1.6. If it’s the ippbx, then I have no idea.
Lots of good information is available from avayausers.com/index.php
