Cisco Emergency Responder license ties to specifc phones

Hello Guys,

 

One of our customers currently has 20 ER User licenses and they have around 50 IP Phones total. They want to tie only 20 IP Phones to be tracked by Cisco Emergency Responder and the other 30 IP Phones not to be tracked by CER so that they don't exceed the licenses limit. Is this possible and how can we achieve this?

 

Appreciate your help

 

Thanks

Hi,

You can achieve this by using IP Subnet Phone Tracking. In your case, you need two IP Subnets, one for 20 Phones which you want to track and one for 30 Phones which you do NOT want to track. Configure these IP Subnets in CER under ERL Membership > IP Subnets. 

  • For IP Subnet that you want to track, do not select checkbox for "Do not track phones under this IP Subnet".
  • For IP Subnet that you do NOT want to track, select checkbox for "Do not track phones under this IP Subnet"

With this configuration, CER will track only 20 IP Phones and will count for licensing. 

For your reference, here are screenshots of my licenses for CER:

Because of the SNMP connection between CUCM and CER, CER will always know about all of the phones in CUCM. I don't know of a way to get around that.

You can have some automatically tracked and some not by setting up subnet or switchport tracking correctly. But if you are asking if there is a way for CER to only "see" the 20 phones you want tracked and not the others, I don't believe there is any way to do that.

I had forgotten about that checkbox. Thanks @Vaijanath Sonvane !

The only caveat to that is that you must be running CER v11 or later for your licensing concern to be addressed. In earlier versions phones discovered but not tracked because of this checkbox still increased your license count.

The checkbox has been around for a while. My comment was about licensing, since that was the original question. I have edited my response to be more clear.

Yes, this feature was added in version 10.0 or 10.5 if I recall and was added explicitly for this reason as for years customers who had a need for an e911 solution at only some locations requiring e911, yet CER required full licensing of all cluster phones, which was very unfortunate and expensive for some customers.
