Example XML Configuration:

Taken from a Snom 710 - Here we have config with "Read Write" permissions, ideal while you are setting things up:

Handy Config Tricks

By making these volume settings "Read Only", you can adjust the volume "during a call" or "outside of a call" and it returns to pre-configured value automatically:

<vol_speaker perm="R">9</vol_speaker>
<vol_ringer perm="R">9</vol_ringer>
<vol_handset perm="R">9</vol_handset>

XML Permission Flags:

Flags are defined as "permission flags" in the string "perm" within XML tags. Valid values are:

perm="!": The configuration parameter can be changed by the user. However the parameter value will only be stored if that parameter has not been changed yet by the user.
perm="R" or perm=" ": The configuration parameter becomes write-protected (read only).
perm="RW" or perm="": The configuration parameter can be changed but will be overwritten on reboot.

Notes

Don't forget to set the HTTP and ADMIN passwords for security.

Firewall & Security

• You will also want to set up firewall rules, as per the VoIP Firewall page.
