Integration SPA50x with CUCM 8.0

Unanswered Question
Aug 31st, 2010

I need to integrate Cisco SPA50x Phones IP with CUCM 8.0. But, I don't know what license (DLUs) to order: if LIC-DM-DL or LIC-3PTY-DL, because I don't know exactly if CUCM will be recognize the SPAs like Cisco IP Phone or third-party phone IP. In addition, how many DLUs each SPA50x will be to consume. Could somebody help me with this questions, please ? I need to know this with urgency.

Since this moment, I'm very thankful for who can help me.


I have this problem too.

Hi, Steve,

Firstly, thanks for your help.

But, if SPA50x supports RFC 3261 - SIP, it should register in the CUCM as a SIP phone, correct ?

Even if I only use the SPA to talk via IP without other features or resources.

Because in my understanding, it doesn't make sence Cisco has phones IPs that doesn't work with Cisco PBX IPs.

If I'm right, how do I do with this issues about DLUs ?

Can you help me about this, please ?

The only CUCM alternative available would be Call Ctrl Call Manager:

Call Ctrl supports all the SPA IP Phones which in clude SPA500, SPA300 and SPA900. It is required the are running in SIP mode. Our latest release supports the phone directly so it doesnt matter what type of pbx you have. If you have any problems contact our support.
