Registration And Authentication; Ip Address And Settings Reuse - Avaya 9600 Series Installing And Administering

You can restrict the IP addresses from which the deskphone accepts SNMP queries with the
SNMPADD parameter. You can also customize your community string with the SNMPSTRING
parameter. For more information, see Chapter 5: Administering DHCP and HTTP servers .
SNMP is disabled by default. Administrators must initiate SNMP by setting the SNMPADD and
SNMPSTRING parameters appropriately.
For more information about SNMP and MIBs, see the IETF website: http://www.ietf.org. The Avaya
Custom MIB for the 9600 Series IP Deskphones is available for download in *.txt format on the
Avaya support website: http://support.avaya.com.
The SIP software release 2.6 MIB is different than that of release 6.5 MIB. Ensure to download the
MIBs applicable to your environment.

Registration and authentication

9600 Series IP Deskphones require an outbound proxy SIP (OPS) extension on Communication
Manager and a login and password on Session Manager to register and authenticate.
For the SIP Deskphones to work properly, you must specify the correct domain name on the IP
Network Region screen of Communication Manager.
For more information, see the following documents at the Avaya Support website
support.avaya.com:
• For information about the IP Network Region screen, see Administering Network Connectivity
on Avaya Aura

• For information about the registration process, see Maintaining Avaya Aura
Manager and Troubleshooting Avaya Aura
administration documentation.

IP address and settings reuse

After a successful registration with a call server, the IP address of the deskphone and the
parameter values are saved in the non-volatile memory of the deskphone. The deskphone can
reuse the saved parameters if the DHCP or HTTP/HTTPS server is not available for any reason
after the deskphone restarts.
IP Address reuse was added to prevent infinite looping when separate DHCP servers are used for
voice and data VLANs, and a response is received from the DHCP server on the data VLAN, but
not on the voice VLAN.
