[cisco-voip] SNMP management Call Manager server

[Voll, Scott]

I think you have a few options:

 

Nat the CM / Routers etc to public.

 

Create a VPN connection from the NOC to the customer.

 

Place the SNMP server on Customer premise and open that to the NOC.

 

I would not suggest changing IPs on the CM. 

 

Just my 2 cents.

Hi

 

Deployed a call manager solution for a customer. Used private addressing
for the phones, voice gateways and Call Manager / Unity voicemail. The
customer now wants to outsource the management of the IPt elements of
the solution. One of the partners they contacted told them that they
will have to use public IP addressing on the Call Manager server and
voice gateways in order to allow the partner to manage the solution from
a central noc at the partner. This should not cause a major problem for
the voice gateways where one can add a loopback with a public IP to
allow reachability from the NOC without any NAT etc. However, I am not
too sure how this will be handled on Call Manager. The customer is not
keen to have Call Manager on a public IP and also not keen to re-address
the Call Manager / Unity connection servers so that they can be managed
from a noc based HP openview / similar platform via SNMP.

 

I know cisco has IP Telephony management products available that can be
placed onsite at the customer to manage all devices (operations manager,
service level 

manager etc.). 

 

QUESTION

=========

Without these solutions like onsite ops manger / service level manager
- what options are available to manage call manager via snmp from a
service provider NOC - if possible - without having to change away from
the private address the customer is using already. I know that NAT and
SNMP causes problems - is this still the case with cisco's
implementation - or would it be possible to have static NATs on a cisco
router at the customer premises to NAT the Call Manager and Unity server
IPs to unique public IPs so that they can be managed by a remote noc.

 

Not a network management fundi - any advice will be appreciated.
