How lots of phones and listing quantities can be configured on Cisco Unified Communications Manager Express by default?
Of course, by default, no ephones or listing numbers can register. Prior to carrying out nearly anything else, the pursuing configuration is necessary:
This let up to 4 phones to sign-up / be configured and 8 directory figures.
If you you should not do this, the router will not allow for ephones or ephone-dns to be established. Here is an example of what would come about:
ephone tag 1 exceeds max-ephones
dn 1 exceeds max-dn
The maximum selection of ephones and ephone-dns that can be configured is system dependent. Right here is an instance of my router that can guidance 30 telephones with up to 150 ephone-dns:
Highest telephones to support
Most directory numbers supported
Cisco have a wonderful document exhibiting you how lots of ephones/dns are supported on precise platforms. Have a glance below
As an example, employing CME variation 4.3:
The 2801 supports 25 telephones and 120 ephone-dns
The 2811 supports 35 phones and 144 ephone-dns
The 2821 supports 50 phones and 192 ephone-dns
The 3845 supports 250 telephones and 720 ephone-dns
(There are others, you should refer to the url earlier mentioned for a entire record)
Cisco also suggest that you only empower the selection of ephones and ephone-dns for the quantity you have to have, not the most the system can support. The reason is that when a ephone / ephone-dn is produced, it takes advantage of up memory on the router. Never just build them since you can! Generate only what is needed.
To your achievement!
