Avaya 3631 - Manual (Page 17)

3631 Wireless Telephone Administrator Guide 17
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.
Initial Configuration: Getting to Dial Tone
There are two main approaches to initial provisioning of the 3631 telephone:
• Open access point
1. This approach requires an AP with no security, broadcasting its SSID on the
network.
