Avaya 3631 [18/31] Ip address mapping screen

3631 Wireless Telephone Administrator Guide 18

All involved stations should have consistent settings for „Direct IP-IP Audio

Connections“ and „IP Audio Hairpinning“. If a firewall prohibits direct end to end

streams, then „Direct IP-IP Audio Connections“ must be set to „No“.

IP Codec Set Screen

Use the Communication Manager ‘change ip-codec-set x’ command to specify the codecs

used by the 3631 phone and other VoIP resources. The following codecs are supported

by the 3631 phone:

• G.711

• G.726A-32K

• G.729A

• G.729AB

Set „frames per packet“ to 2 or 3, because the 3631 only supports 20ms packets and 30

ms packets.

IP Address Mapping Screen

Use the Communication Manager ‘change ip-network-map’ command to assign the IP

addresses for your 3631 telephones to their appropriate IP network region.

IP Network Region Screen

Use the Communication Manager ‘change ip-network-region x’ command to configure

network region communication settings for the 3631 phones and other VoIP resources.

The first page is used to modify the audio and QoS settings. In the AUDIO

PARAMETERS section, use the Codec Set field to specify the codec set used within the

region. The UDP port fields specify the UDP port range used for sudio packets. Ensure

that no conflicting port filtering is active in a firewall or in the Access Point security

settings.

If you are using WMM for QoS on the 3631 phone, use the DIFFSERV/TOS

PARAMETERS to set the DiffServ (DSCP) values for Audio and Call Control. The

3631 phone receives these values when it registers with the call server; and it uses these

values to set the 802.11e User Priority and Access Category values for the Audio and

Call Control (Signaling) packets it transmits. For additional information, see the “QoS”

section of this document.

The wireless zone may use several network regions. Nevertheless the same codec sets, or

different codec sets with a common subset and order of codecs, must be used. Check

page 3 „inter network region connection management“ and specify the correct codec set

to be used when communicating between regions.
