Why the Avaya G860 Media Gateway

The Avaya G860 Media Gateway allows call center customers to consolidate facilities and
reduce communications costs. The media gateway concentrates incoming PSTN traffic over
several DS3 lines while supporting VoIP telephony in the call center itself.

The use of voice over IP (VoIP) and conversion from DS1 to DS3 lines eliminate the large
number of DS1 interfaces required to support the same amount of call traffic. The Avaya G860
Media Gateway supports up to 6000 channels of session IP (SIP) VoIP telephony. It uses N+1
redundancy of media gateway, Ethernet switch, shelf controller, and power supply modules to
achieve high availability in mission critical applications.

In the sample call center configuration shown here, a simulated PSTN delivers customer calls
using a DS3 interface to the Avaya G860 Media Gateway. The media gateway establishes calls
with the Avaya S8720 Media Server via SIP signaling and routes all Real-time Transport
Protocol (RTP) traffic to the appropriate media resources within the Avaya G650 Media
Gateway or Avaya endpoints. Avaya Communication Manager delivers the calls to an agent
phone.

Call routing configuration

Similar to Avaya Communication Manager , the Avaya G860 Me dia Gateway must be configured
with SIP and DS3 trunks and with rules to route inbound (DS3 > SIP) and outbound (SIP > DS3)
calls based on information in the incoming call request. You may want to load balance the
incoming traffic from the Avaya G860 Media Gateway across multiple TN799DP C-LAN circuit
packs in the Avaya G650 Media Gateway. All outbound calls should be routed from the
TN799DP C-LAN circuit packs to the Avaya G860 Media Gateway, which routes them to the
DS3 interface on the PSTN side. The routing rules are summarized below.

Avaya G860 Media Gateway configuration

Call Type Routing

Condition

(G860 to/from C-LANs)

Inbound DS3 > SIP > C-LAN1 Last digit of calling

number = 0-4

Inbound DS3 > SIP > C-LAN2 Last digit of calling

number = 5-9
Inbound DS3 > SIP > All All
Outbound C-LANs > SIP > DS3 All

The routing list also has the property that if a call cannot be successfully routed to the
destination specified by a matched rule, then the next rule that matches is used to attempt to
route the call. This can be used implement a failover strategy if one of the TN799DP C-LAN
circuit packs is not responding or not available. For this feature to work most effectively, we
recommend that during maintenance operations, the Ethernet interface be disabled on a
TN799DP C-LAN circuit pack as well as busying it out.

d. Verify that the SIP trunks are up between the A vaya Communication Man ager and the

G860 Media Gateway and that the transport protocols and ports match (TLS and

5061).

Verifying call routing

Verifying call routing means making calls within a session Internet Protocol (SIP) environment
and between SIP and the public switched telephone network (PSTN).

In general, if a SIP device in the network does not receive an expected response to a SIP
message it has transmitted, the standard procedure is to retransmit that message t an
exponentially decreasing interval (0.5 s, then 1 s, etc.) up to 6 more times. Look for this
behavior at various points in the call routing pat h if calls are not successful or if calls only remain
established for about 32 s. Most likely, the expected message was not routed properly because
of NAT, dial-peer, DNS, or firewall configuration errors.

1. Make calls from a telephone on the PSTN to a SIP telephone. If inbound calls fail, verify
that the proper Tel to IP routing rules were defined to support routing SIP calls to the
appropriate C-LANS.

2. Make calls between SIP telephones registered within each proxy to verify successful call
completion.

If outbound calls fail, verify that the proper IP to Tel routing rules were defined to support
routing SIP calls to the appropriate DS3/DS1.

3. Log into a SAT session on the media server.

4. Type list trace station to verify that the call is being properly routed through the
SIP trunk to the G860 Media Gateway.

5. Change the transport protocol to TCP on the SIP trunk and use a SIP-capable protocol
analyzer to monitor the signaling messages.

6. Type change signaling group and press Enter.

7. Change the following fields:

● Transport Method: tcp

● Far-end Listen Port: 5060

8. Log into the G860 Media Gateway.
