SPA9000 Voice System Installation and Configuration Guide for Web UI
Q. I am trying to upgrade a phone with a computer that is connected to the PC
port. The upgrade is not successful.
A. You cannot perform a firmware upgrade from a computer that is connected to
the phone that you are upgrading. The phone reboots several times during the
upgrade process, and as a result the firmware cannot be retrieved from the
computer. Unplug the computer from the phone and instead connect it to an
available port on the switch.
Q. I manually entered the proxy address into my phone configuration but it
doesn't register with the SPA9000.
A. Verify that you entered the correct SPA9000 IP address and the correct proxy
listen port (default 6060). For example, enter 192. 1 68.0. 1 :6060 in the Proxy location
of the SPA941.
Q. Why can't I register the FXS ports to an outside proxy?
A. The FXS ports are registered directly with the SPA9000; no options exists for it
to connect to another proxy.
Q. Why do only four SPA900 series clients register?
If you need to add more than four phones, install the SPA9000 firmware version
5.2.5, which supports up to 16 IP phones.
Q. The IP phone can make internal calls to other IP phones and analog phones
but it cannot make external calls.
