Offer Gruu; Offer Mpo; Filter Packets From Registrar; Authentication For Sip Reboot - Snom 360 Manual

Settings

Offer GRUU

This setting is used to toggle the support for GRUU (Globally Routable
User agent URL's) in SIP. Several phones with same account can be
identified by this GRUU-ID from the proxy which is unique to a phone
and stays the same even after reboot.

Offer MPO

Using this setting, the user can turn the Media Path Optimization
support on or off. This makes only sense in case you have MPO
supporting session border controller devices in your environment (i.e.
from Jasomi).

Filter packets from Registrar

If set to "on" all SIP packets which are not coming from the
registrar/proxy will be ignored. This is for security reasons by default
set to "on". This can cause big trouble in an environment where SIP
packets from other sources have to be accepted for proper functionality
also!

Authentication for SIP Reboot

This setting enables/disables a challenge response for a remote reboot
request.

Authentication for SIP Check-Sync

Turning this setting on enables a challenge response for a Check-Sync
request.
Session Refresher
To change the SIP session refresher support from Client to Server
refresh, this option can be used. That means during a call in case it is
not already negotiated, you can specify here which party of the call
(either the client or the server), is refreshing the current call with Re-
INVITE messages.
UPDATE
Update Policy
You can select the best possible update policy you would like to adopt
for your phone.
"Update automatically": does not ask again, if you are really sure to
update.
"Ask for update": asks, if you are really sure to update firmware or
bootloader.
