Hi,
We have 2 Cisco 2801 configured with MGCP that register ok but always give "TFTP dowanload failed".
When I debug "ccm-manager config-download" its says
*Jul 16 10:39:11.795: cmapp_xml_tftp_download_file: Unable to read file tftp://1
0.0.5.250/EAA_AERO_R1.euroatlantic.aero.cnf.xml, rc=-2
*Jul 16 10:39:11.795: cmapp_xml_get_xml_file: Could not read file tftp://10.0.5.

Our main office Cisco 2851 has no problem with this.
Can somenone help me with this?

How does you config look like? Especially the ccm-manager part.

Hi,
Make sure that IP address in your
ccm-manager config server 171.69.103.225
points to the ip address of your tftp server/publisher
In the above example, 171.69.103.225 is my tftp server/publisher

Always remember - if you have loopback addresses as bind interfaces for MGCP you may also have ACL's/FW's preventing voice subnets from accessing data network segments for security purposes, Remember to use the command:
ip tftp source-interface Loopback(#)
Or you may get tftp / config-download issues as the outbound traffic from the Voice Gateway will use the outbound interface of the router for TFTP and from potentially a non Voice IP address as the source IP (rather than an binded MGCP loopback for signalling / rtp). This also is a cause of "registration rejected" in CUCM.
This is very typical on ISR routers that are not only used as a voice gateway when you want other network ranges to use for EIGRP / OSPF / BGP neighbour addressing and separate ranges for voice for easy QoS management.
And of course the most common MGCP registration issue is ensuring hostname + domain matches in sh ccm-manager: (MGCP Domain Name: HOST.domain first line of output) in CUCM.
