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 34-4: 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).
To configure this feature, you need to configure the SIP Interface of the proxy server with a
special UDP port range, and use tag-based routing with Call Setup Rules to specify the
exact UDP port you want assigned to each SIP entity (IP PBX), from the SIP Interface port
range. The following procedure describes how to configure the device to use a specific
local UDP port per SIP entity on the leg interfacing with a proxy server that is common to
all the SIP entities. To facilitate understanding, the procedure is based on the previous
example.

To configure specific UDP ports for SIP entities communicating with common
proxy server:
5. Open the SIP Interfaces table (see Configuring SIP Interfaces on page 357), and then
configure the following SIP Interfaces:
