Similarly there is particular no restriction for the Jabber SDK to have a DNS host name for any of the UCM/TFTP locations - a simple IP address can work. I would definitely not expect UDS to internally obtain a host name from UCM, then do a DNS resolution and pass the resulting IP to a UDS request. It is possible to fully install/configure a UCM cluster using only admin provided IP addresses (not using DNS host names) - common in lab environments. The URLs returned here should reflect the configuration in UCM re hostname/IP. Please refer - Trivial File Transfer Protocol (TFTP) for related information. If you are planning to use a stand alone tftp server then it is good to have dial plans, locales and device packs uploaded on this standalone TFTP server, in case the server roles were adjusted at a later point in time. It builds configuration files and serves firmware files, ringer files, device configuration files, and so forth, to endpoints.īy architecture, the TFTP server would be the one pushing out the firmware load and to the phones. The Cisco TFTP service is a file serving system that can run on one or more Unified CM servers.
CISCO TFTP SERVER SOFTWARE
Within a Cisco Unified CM system, endpoints such as IP phones rely on a TFTP-based process to acquire configuration files, software images, and other endpoint-specific information. so getting hostname will be possible only if DNS is enabled. If DNS is enabled, Cisco still highly recommend that you do not use DNS names in the configuration of the IP Communications endpoints, gateways, and Unified CM servers. (From cucm serviceability page.)ĭuring installation of the publisher and subscriber, Cisco recommend that you do not select the option to enable DNS unless DNS is specifically required for system management purposes. I think by knowing the hostname for which the tftp service is enabled you can find the server ip. What i understand from your question is that you are having a cucm cluster 5 servers with 1 publisher and 4 subscribers and you would like to know which is the TFTP server ip.
