Network Requirements
For the H.323/SIP IP Gateway server to communicate with the Audio Server, confirm that your network
meets the following requirements:
meets the following requirements:
•
The Audio Server and the H.323/SIP IP Gateway server must be located on the same subnet.
•
The H.323/SIP IP Gateway server must be inside the corporate firewall and must be able to access
the softswitch (for example, Cisco Unified Communications Manager, H.323 gatekeeper, or
Cisco SIP Proxy Server) by using H.323 or SIP.

•
The H.323/SIP IP Gateway server must be able to open a TCP connection on port 5003 when
connecting to an Audio Server.

•
The secondary Ethernet connections—those that are connected to the MA Blade and not the second
Ethernet port on the CPU card—on the Audio Server must be connected to the same subnet as the
corporate network to which your Cisco Unified IP Phone is connected.

•
The Ethernet switch port or any other network devices to which the MA Blade connects directly
must be set to fixed 100Base-TX full duplex; if not, you may experience decreased voice quality.
must be set to fixed 100Base-TX full duplex; if not, you may experience decreased voice quality.
•
If G.711 codec is configured, a dedicated 100 Mbps subnet is required for each MA-16 connection;
if not, the voice quality may be degraded.
if not, the voice quality may be degraded.
•
From the H.323/SIP IP Gateway server standpoint, the IP address of the Audio Server must not be
translated by using a Network Address Translation (NAT) routing scheme.
translated by using a Network Address Translation (NAT) routing scheme.
•
Connectivity between the H.323/SIP IP Gateway server and the Audio Server must be high quality
and not subject to interruptions because of traffic congestion. Any time the round-trip latency
exceeds 100 milliseconds or there is more than 1-percent packet loss, expect a noticeable reduction
in service quality.
