How lots of telephones and listing figures can be configured on Cisco Unified Communications Manager Specific by default?
Certainly, by default, no ephones or directory numbers can register. In advance of doing anything else, the pursuing configuration is required:
This allow up to 4 phones to register / be configured and 8 listing numbers.
If you don’t do this, the router will not allow ephones or ephone-dns to be made. Below is an illustration of what would occur:
ephone tag 1 exceeds max-ephones
dn 1 exceeds max-dn
The optimum range of ephones and ephone-dns that can be configured is system dependent. Here is an illustration of my router that can guidance 30 telephones with up to 150 ephone-dns:
Maximum telephones to assistance
Greatest directory figures supported
Cisco have a good doc exhibiting you how a lot of ephones/dns are supported on distinct platforms. Have a glance listed here
As an illustration, utilizing CME model 4.3:
The 2801 supports 25 telephones and 120 ephone-dns
The 2811 supports 35 phones and 144 ephone-dns
The 2821 supports 50 telephones and 192 ephone-dns
The 3845 supports 250 telephones and 720 ephone-dns
(There are other individuals, please refer to the connection over for a entire record)
Cisco also suggest that you only permit the amount of ephones and ephone-dns for the amount you involve, not the most the system can help. The motive is that when a ephone / ephone-dn is created, it employs up memory on the router. You should not just make them for the reason that you can! Make only what is needed.
To your achievements!
