Hello there,
I am adding a subscriber to a CM cluser in 5.13
I get the following error/screen
-----
COnfiguration validation with CM-PUB (10.11.1.110) failed
Could not send/recieved UDP packets to publisher on port 8500
-Is network connection to CM-PUB up?
-Is the MTU Size correct for this network
-Doe the network allow packet fragments
------
I can ping the servers,
any suggestions?
thanks!

In this page you can find the installation guides of all version of Cisco CallManager:
http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_installation_guides_list.html
For version 5.1(3):
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/install/5_1/cmins513.html
When you are installing the CallManger you can see the version on the top of screen and with the Web Administracion in the menu About.
When you buy a Cisco CallManager it comes with the DVD of installation. Also, you need licenses for the Servers and IP Phones (DLUs).
I recommend you reading the installation guide, Cisco explain everything.

Hi Martin,
both server's are in the same network? you are using a IPSEC tunnel? if the answer is yes, maybe you need to apply the following command to the wan interface:
"crypto ipsec df-bit clear"
