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: 126.96.36.19900-52
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.
The thread is quite old and you seemed to have made the phones work with CUCM.
We are trying to do the same and somehow the phones are not working
Can you please help us with the steps you followed to make these phones work
Thanks in advance
