Udp Port Selection; Network Audio Quality Display On 4600 Series Ip; Telephones - Avaya
4600 Series Administrator's Manual

The Avaya IP Telephones' DiffServ values will be changed to the values administered on the call
server as soon as the phone is registered. For more information, see the document titled
Administration for Network Connectivity (555-233-504). Unless there is a specific need in your
enterprise LAN, we do not recommend you change the default values.

UDP Port Selection

Some data networks include equipment that can perform UDP port selection. This is a mechanism
by which packets with port numbers in a given range are given priority over packets with port
numbers outside that range.
To support UDP port selection, the 4600 Series IP Telephones can be administered either from the
network via appropriate administration of the DHCP or TFTP servers, or at the telephone itself via
dialpad input. Specific implementation details for local administration are in the 4600 Series IP
Telephone Installation Guide, and, for remote administration, in
and Application Files, on page
on the TN2302AP board. This port number can be used to administer routers, etc. that support
UDP port selection, to maximize the priority given to the voice packets being exchanged between
the PBX and the telephone.
The default value for MCPORT is 1719. The switch must be administered to use a port within the
proper range for the specific LAN, and the IP Telephone(s) will copy that port. A related parameter
is PORTAUD, which is the RTP port used by the switch. In accordance with standards RFC 1889
and 1890, the IP Telephone uses a default value for PORTAUD of 5004. MCPORT and PORTAUD
are both administrable (see
4-28).

Telephones

As of Release 1.7 for the 4620 and 4630/4630SW telephones, and as of Release 1.8 for the other
4600 Series IP Telephones, the telephone is by default administered to offer the end user an
opportunity to monitor network audio performance while on a call. The user guides for each phone
go into specific detail on how the user gets to the appropriate screen; this document tells you what
the end user can see, and what it means.
