We have just changed our old Philips digital telephone system to Cisco's VoIP system. So we don't know much about this thing.
From another office, we got a lot of telephones -- Siemens OpenStage 15 HFA.
We would like to know how to configure these telephones to work with Cisco's VoIP system. I mean, what device should we take?
Here's the info about our Cisco system: System version: 18.104.22.16800-52
Thanks in advance.
You can try configuring them as basic or advanced SIP devices. Be ware, that you will need to find a way to inform the phones abouf the CUCM.
Thanks for your reply.
OK, I see, there are "Third-party SIP Device (Advanced)" and "Third-party SIP Device (Basic)" in the list of "Phone Type".
I'll try it.
