## Questions & Answers

**Q: What type of lithium battery?**
A: No battery in this phone.  This is a POE VOIP telephone - it is not cordless.

**Q: They come with the back stands?**
A: yes they do

**Q: Does this model compatible with third-party pbx system like freepbx out-of-the-box?**
A: Hello Ethan,

The Cisco CP-7821 IP phone can work with third-party PBX systems when you replace the firmware with version 10.3(1). You will need to upgrade the firmware and use the SIP protocol only to support the third party PBX. However, this will not work out of the box and you have to upgrade the firmware.
