Figure 110: Sample packet capture output
The
preceding figure shows the packet list. The first four columns show the packet
number, time and the addresses of the hosts involved. Because Wireshark
understands SIP, it is able to identify the packets as SIP in the Protocol column and
give detailed information in the Info column.
A cursory examination of the information in this figure shows that the same three
packets repeat themselves five times. First, the Mediation Server sends a SIP
INVITE message to the Media Gateway, which is used to open a conversation. Next,
the Media Gateway responds with “404 Not Found” to which the Mediation Server
responds with an ACK. From this trace it is likely that the OCS Client through the
Mediation Server is trying to reach a non-existent user or the Secure Router 4134
is not configured to handle this number.
Re-imaging the Mediation Server Module
If you lose the administrator password for your Mediation Server Module (and have no other
account
with administrator privileges), or if the software image becomes corrupt on the module,
you must re-image the module.
Avaya strongly recommends the following procedures to protect the software on the Mediation
Server Module:
• Create at least one additional user account with administrator privileges on the Microsoft
Windows Server 2003 running on the Mediation Server Module for OCS. If you lose or
