34.2.2 Configuring Specific UDP Ports using Tag-based Routing

You can configure the device to use a specific local UDP port for each SIP entity (e.g.,
PBX) communicating with a common proxy server (e.g., ITSP). The figure below illustrates
an example scenario of such an implementation, whereby the device uses a specific local
UDP port (e.g., 6001, 6002, and 6003) for each IP PBX, on the leg interfacing with the
proxy server:
Figure 34-5: Example of Assigning Specific Ports using Tags
For each IP PBX, the device sends SIP messages to the proxy server using the specific
local, UDP port on the leg interfacing with the proxy server. For SIP messages received
from the proxy server, the device routes the messages to the appropriate IP PBX according
to the local UDP port on which the message was received. On the leg interfacing with the
IP PBXs, the device uses the same local UDP port (e.g., 5060) for all IP PBXs (send and
receive).
