[cisco-voip] UCM - CUBE trusted IP address

[Daniel Pagan]

Two options...

1.       Ensure the two nodes (7 and 8) are in the CCM Group contained in the assigned DP on this trunk.

Or


2.       Enable it to run on all active nodes.

Either way would allow the SIP daemon for this trunk to run on Server7 and Server8, which is essentially what's needed.

In this scenario I see nothing wrong with turning this on, but I'd be careful if enabling this between UCM and 3rd party PBXs or applications where only a limited number of SIP UA entries can be defined... can lead to a situation where a SIP call is sourced from a CUCM node that's not defined at the remote side, leading to call failure. Aside from that, for inbound calls, the call will be rejected if the SIP INVITE is sent to a CUCM node not running the SIP daemon for this trunk. For outbound, the SIP INVITE should source from the node where the Route List used for the call is registered (assuming #1 or #2 above is correct).

Hello Group

we run a CUCM Cluster 9.1(2) with a SIP Trunk (CUBE) to our telephony  provider.
Our cluster has 8 Servers (1 Pub / 7 Sub).
On the CUBE we have three dialpeers pointing to three different subs for redundancy:

dial-peer voice 1000 voip
destination-pattern
session target ipv4: Server5

dial-peer voice 1001 voip
destination-pattern
session target ipv4: Server4


dial-peer voice 1002 voip
destination-pattern
session target ipv4: Server3


On the UCM we have a SIP Trunk configured with a device that contains Server3, Server4 and Server5 in its CUCM Group.
All IP Phones register to Server4 or Server5.


We now have the problem that Server4 has sometimes a pretty high CPU load (Code yellow).


I want to change the dialpeers on the CUBE so that they point to Server7 and Server8 to reduce the load on Server4.

What do we have to change on the UCM if we change the dial-peer voice 1000 and 1001 on the CUBE to
dial-peer voice 1000 voip
destination-pattern
session target ipv4: Server7


dial-peer voice 1001 voip
destination-pattern
session target ipv4: Server8


Thanks a lot
Regards Reto
