All these ports are configurable on the Cisco UCM, except for TFTP. These are the default
values and should be modified if they are modified on the Cisco UCM. For example, 3804 is the
default port for the CAPF Service. This default value should be modified if it is modified on the
Cisco UCM.
If NAT is configured for the TFTP server, the NAT configuration must be configured prior to
configuring the tftp-server command under the phone proxy.
If NAT is configured for the TFTP server or Cisco UCMs, the translated "global" address must be
used in the access lists.
When the Skinny inspection global port is configured to use a non-default port, then you must
configure the nonsecure port as the
Therefore, if global_sccp_port is 7000, then the global secure SCCP port is 7443. Reconfiguring the
port might be necessary when the phone proxy deployment has more than one Cisco UCM and they
must share the interface IP address or a global IP address.
