Volume levels for the ringer, speaker, handset, and headset are controlled from the volume bar on the phone itself.

• Auto-answer Switchboard initiated calls. This sets your phone to automatically answer Switchboard-initiated calls. If you click on a Switchboard phonebook entry, normally your phone rings and you have to pick it up, then Switchvox dials the number for that entry. If this box is checked, your phone rings and then automatically goes to Intercom mode and answers the Switchboard, and you hear the phone ringing for the call to your phonebook entry.

• Phone Password. Enter your phone password and verify it. (See also the “Settings” article.) This is the Authentication Password that your SIP phone uses for registration with Switchvox. This password may be different than the password used to administer the SIP phone from the phone itself. Also, this password does not change when this extension's voicemail password changes.

• ​Phone NAT Traversal. This option controls how Switchvox communicates with the phone if it is behind a router performing Network Address Translation (NAT). The following options are available:

  • Always. Select if you are unsure if the phone is behind a router performing NAT.

  • No. Select if Switchvox is behind NAT but the phone is not.

  • Never. Select to prevent attempts to translate even if the handset requests it with the report tag.

  • Route. Select to send responses symmetrically, but not to include the rport tag in the Via header.
