Echo Cancellation

When set to Y, Echo cancellation is enabled.

Channel specific Setting

Channel specific settings mentioned below.

DTMF Method

This parameter specifies the mechanism to transmit DTMF digits. There are7 modes

supported: in audio which means DTMF is combined in audio signal (not very reliable

with low bit-rate codec), via RTP (RFC2833), or via SIP INFO. Multiple DTMF

transmission schemes can be selected.

• 1 – in-audio

• 2 – RFC2833

• 3 – in-audio and RFC2833

• 4 – SIP Info

• 5 – in-audio and RFC2833

• 6 – SIP Info and RFC2833

1. 7 – in-audio, RFC2833, and SIP Info

No Key Entry Timeout

Default is 4 seconds.

Local SIP Listen Port

Default is ch1-8:5060++;. The ++ indicates increments by 2, so port 1 is set at 5060,

port at 5062 and so on. This setting can be used with Round Robin and/or Flexible

setting below to configure different ports to be placed under different Round Robin

groups.

SRTP Mode

Default is disabled for all ports. The user can select to either enable it but not force it

or force it on an individual port basis. When used the communication will be sent

using Secure RTP.

Round Robin and/or

Flexible

Default is rr:1-8;

The syntax is pretty straight-forward here. The rr stands for Round Robin and the

numbers stand for the ports that belong to that round robin group.

For example:

rr:1-8; -> Round robin within the first 8 ports i.e. outgoing calls will be forwarded to

the next available port within the group of ports 1 to 8.

rr:1,3-6,8;rr:2,7; -> Round robin within port 1,3,4,5,6 and 8; Second round robin group

within ports 2 and 7 i.e. outgoing calls to ports 1,3,4,5,6 and 8 will be forwarded to the

next available port within this group ONLY. Outgoing calls to port 2 and 7 will be

forwarded to the next available port between ports 2 and 7 ONLY.

** In order to terminate a call on FXO port 2 or 7 you will need to change its Local

SIP Listen port accordingly.

Prefix to specify Port

(1 stage dialing method)

Default is 99.

Syntax to USE this feature: prefix# (that is 99) + ch# (could be anything from 1 to 8) +

dialing# will result in this call forwarded to FXO port (ch#) immediately.

1 2 ... 20 21 22 23 24 25 26 27 28 29 30 ... 35 36
