Edit Alias Dialog Box
The Edit Alias dialog box lets you change an alias value assigned to the hunt
group. Edit the alias in the Value box and click OK.
Aliases should be specified by their fully qualified dial string. For example, to
specify that H.323 callers can call the hunt group by dialing 1234, enter
1234
.
To specify that SIP callers can call the hunt group by dialing 1234, enter
sip:1234@mydomain.com
.

Device Authentication Device authentication enhances security by requiring devices registering with
or calling the Polycom DMA system to provide credentials that the system can
authenticate. In turn, the Polycom DMA system may need to authenticate itself
to an external SIP peer or gatekeeper.
All authentication configurations are supercluster-wide, but note that the
default realm for SIP device authentication is the cluster’s domain as specified
on the Network Settings page (or
sip.dma
if no domain is specified). See
“Network Settings” on page 64. This allows each cluster in a supercluster to
have its own realm for challenges.
The Device Authentication page has two tabs, Inbound Authentication and
Shared Outbound Authentication.
Inbound Authentication
On the Inbound Authentication tab, you can:
•Configure specific SIP digest authentication settings for SIP devices.
•Maintain the Call Server’s local inbound device authentication list. This
list is used for both H.235 authentication (H.323 devices) and SIP digest
authentication (SIP devices).
•Click the Signaling settings link to go to the Signaling Settings page,
where you actually enable device authentication for H.323, SIP, or both
(see “Signaling Settings” on page71).
