No Audio

One or all parties on a call are experiencing no audio. Check the following:

• Ensure Mute button is off on all phones

• Communication Manager ‘Station’ form. 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“. Use ‘Status Station’ command to check results.

• Communication Manager ‘IP-Network-Map’ form. Ensure all endpoint addresses are

assigned to appropriate IP network regions

• Communication Manager ‘IP-Network-Region form. Ensure the UDP port fields

specify the UDP port range supported by the endpoint. Ensure that no conflicting

port filtering is active in a firewall or in the Access Point security settings. 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 ensure the correct codec

set is being used if communicating between regions.

• Communication Manager ‘IP-Codec-Set’ form. Ensure the codecs are supported by

the endpoints in the call. The following codecs are supported by the 3631 phone:

o G.711

o G.726A-32K

o G.729A

o G.729AB

Ensure „frames per packet“ is set to 2 or 3, because the 3631 only supports 20ms

packets and 30 ms packets.
