Valid Entry

Usage

y

Enables inter-connection between servers running Avaya Communication Manager. Unavailable if a RAS-Location Request (LRQ) is enabled.

Note:

When the near and far-end servers are running Avaya Communication Manager, this value must match the value administered for enabling the Layer 3 test.

Valid Entry

Usage

T1

U.S., Canadian, and Japanese digital transmission format.

E1

European digital transmission format.

Clustered

Valid Entry

Usage

y

Allows the signaling group to administer Cluster ID.

When it is set to y, the Far-end Node Name field is replaced with Cluster ID field.

n

Does not allow the signaling group to administer Cluster ID..

Connect

To control communications at layers 2 and 3 of the ISDN-PRI protocol, this field specifies what is on the far end of the link.

Available only if Group Type is atm.

Valid Entry

Usage

host

The link connects Communication Manager to a computer.

network

The link connects Communication Manager to a local telephone company central office or any other public network switch.

pbx

The link is connected to another switch in a private network.

Country Protocol

Available only if Group Type is atm.

Valid Entry

Usage

The country code.

etsi

The network service provider uses the protocol of the European Telecommunications Standards Institute (ETSI). Used only if the Signaling Mode is isdn-pri.

DCP/Analog Bearer Capability

Sets the information transfer capability in a bearer capability IE of a setup message to speech or 3.1kHz. Available only if Group Type is atm or h.323.

Valid Entry

Usage

3.1kHz

Provides 3.1kHz audio encoding in the information transfer capability. This is the default.

speech

Provides speech encoding in the information transfer capability.

Direct IP-IP Audio Connections

Allows or disallows direct audio connections between H.323 endpoints. Direct audio connections save bandwidth resources and improve sound quality of voice over IP (VoIP) transmissions. For SIP trunk groups, allows direct audio connections between SIP endpoints. Available only if Group Type is h.323 or sip.

For the SIP Resiliency feature, ensure that the Direct IP-IP Audio Connections field is set to Y.

DTMF over IP

The DTMF over IP field specifies the touchtone signals that are used for dual-tone multifrequency (DTMF) telephone signaling. The DTMF over IP field is available if the Group Type field is set to h.323 or sip.

Valid Entry

Usage

in-band

All G711 and G729 calls pass DTMF in-band. DTMF digits encoded within existing RTP media stream for G.711/G.729 calls. G.723 is sent out-of-band. It also supports the SIP trunks.

in-band-g711

Only G711 calls pass DTMF in-band. The system displays the in-band-g711 option if the Group Type field is set to h.323.

out-of-band

All IP calls pass DTMF out-of-band. For IP trunks, the digits are done with either Keypad IEs or H245 indications. This is the default for newly added H.323 signaling groups.

The out-of-band option enables out of band signaling for the SIP Signaling group. When you select the out-of-band option, Communication Manager sends all outgoing DTMF messages as SIP INFO messages over a SIP signaling group.

This option is interoperable with H.323 networks. You can connect an Avaya non-SIP endpoint or trunk to a voice mail system on the H.323 network that is integrated with Session Manager and Communication Manager through SIP. Examples of Avaya non-SIP endpoints or trunks are H.323, Analog, DCP, and Digital trunks.

Note:

The Layer 3 test should be enabled for an H.323 signaling group type when the Calls Share IP Signaling Connection is enabled and the far-end is Communication Manager. Requires administration of a Far-end Node Name.

The Layer 3 Test must be enabled for the call reconstruction.

Valid Entry

Usage

If you are configuring Communication Manager as a feature server, set the IMS Enabled field to y. Setting this field to y only applies when Communication Manager is being configured as a feature server. If you are configuring Communication Manager as an evolution server, leave the IMS Enabled field set to n.

Valid Entry

Usage

PROGress

Requests the public network to cut through the B-channel and let the caller hear tones such as ringback or busy tone provided over the non-ISDN trunk. Normally-selected value.

ALERTing

Causes the public network in many countries to play ringback tone to the caller. This value is used only if the DS1 is connected to the public network, and it is determined that callers hear silence (rather than ringback or busy tone) when a call incoming over the DS1 interworks to a non-ISDN trunk.

IP Video

Enables or disables IP video capability for this signaling group. Available only if the signaling group type h.323 and sip.

Link Loss Delay Timer (sec)

Specifies how long to hold the call state information in the event of an IP network failure or disruption. Communication Manager preserves calls and starts this timer at the onset of network disruption (signaling socket failure). If the signaling channel recovers before the timer expires, all call state information is preserved and the signaling channel is recovered. If the signaling channel does not recover before the timer expires, the system:

  • Raises an alarm against the signaling channel

  • Maintains all connections with the signaling channel

  • Discards all call state information about the signaling channel

Peer Server

The values for this field are Others, SM, and AMS. The default value is Others. This field is only available if Group Type is sip. If this sip signaling group terminates to an Avaya Session Manager, then Communication Manager will automatically set value in this field to SM if the Peer Detection Enabled field is set to y(es).

If Clustered field is set to y, then the value in this field is automatically changed to SM, and this field will be in read-only mode.

Prepend '+' to Outgoing Calling/Alerting/Diverting/Connected Public Numbers

If you set the Prepend '+' to Outgoing Calling/Alerting/Diverting/Connected Public Numbers field on the SIP Signaling Group screen to y and if Communication Manager uses the public-unknown-numbering table, Communication Manager inserts a leading plus (+) digit in calling, alerting, diverting, or connected numbers. The default value is n.

If the Peer Server field on the SIP Signaling Group screen is SM, the system sets the Prepend '+' to Outgoing Calling/Alerting/Diverting/Connected Public Numbers field to display-only, with the default value of y. If the Peer Server field on the SIP Signaling Group screen is Others, the system sets the Prepend '+' to Outgoing Calling/Alerting/Diverting/Connected Public Numbers field to n and as editable.
