UC540 Phone Licensing

On the UC540 platform, how exactly is licensing done?  If you get a 8 phone license on the defualt kit, my understanding is that this gives you 8 IP phones, 2 teleworker phones, and 4 FXS ports.  So you can technically have 10 IP phones along with 4 Analog for a total of 14 phones (IP and analog) operating at that correct?  Is there some limitation with the teleworker phones?

Now, I understand on CME that there is no hard limit to the amount of ephones and DNs, does this change for the UC540?  Does it limit you to the 8+2 and you can't go higher without a license?


What's teleworker phones? How calculate the phone numbers?

Hi Rob,

Here are the Licensing references. If you need to go above the base license you

would need to add/order the 8-User upgrade;


The Cisco UC 540 includes eight user licenses. These licenses enable the use of

Cisco Unified IP Phones and allow users to access the IP PBX features, including

voicemail. In addition, supplementary user licenses are bundled to help with

deployments that need a few extra licenses. For additional licensing needs,

the L-UC-PRO-8U= may beordered. This increases the existing license count

by eight. Table 5 lists the number of users supported based on the hardware/license

configurations. The UC 540 also has built-in licenses for unified communications features.

Table 4 lists the license count bundled within the system for each feature.

Table 4. Licensing and User Capacity for the Cisco UC 540

License Configuration Description

UC540W-FXO-K9 or UC540W-BRI-K9 8 user licenses, 2 supplemental user licenses

UC540W-FXO-K9 or UC540W-BRI-K9 and one L-UC-PRO-8U= 16 user licenses, 2 supplemental user licenses

UC540W-FXO-K9 or UC540W-BRI-K9 and two L-UC-PRO-8U= 24 user licenses, 4 supplemental user licenses

UC540W-FXO-K9 or UC540W-BRI-K9 and three L-UC-PRO-8U= 32 user licenses, 4 supplemental user licenses

For CME the number of supported phones is based on the Router platform and Memory.

For example: Here is the number for a 2811,2821 and 2851 with CME;

Cisco 2811

Cisco 2821

Maximum Total IP Phones 48

Cisco 2851

Hope this helps!
