[asterisk-users] Polycom Phone Configuration Overrides Not Saved

[Chris Nighswonger]

I have some Polycom 351 on Asterisk 10. On the same box as * I have a tftp
server running to handle configs, etc. The Polycom phones have no problem
grabbing config foo from the tftp server as well as writing log files back
to the server. However, when I use the web-if on a phone to set a custom
ring-tone, the web interface saves the change locally, but throws an error
stating that it cannot write the override config to the tftp server.

A look at a tcpdump shows that the phone indeed attempts to push the file
to the server:

A look at /var/log/messages shows:

Sep  6 10:33:11 pbx1 in.tftpd[18368]: tftpd: read(ack): Connection refused

Now why is it that the phone is refused only when writing the override file?

Note that the only logging difference between a successful and unsuccessful
write is the above line from the message log. The tcpdump looks the same.

Kind Regards,
Chris
