Installing VoIP Issabel in an office with multiple buildings

Hello!

I’m not sure if DIY is the right place to ask this, but I’m in a company that’s trying to migrate from Cisco to another alternative, one of the tools we had in mind was Issabel but there’s a huge doubt I have about it.

With the current cisco configuration we have, the phone can send internet to the computers that have static IP addresses. So the current configuration would be something like:

Wall ----> Cisco Phone ----> PC With Static IP Adress.

The IP address from the Cisco phone is random, one that a DHCP gives them.

So my question is if it possible to mimic this bridge with Issabel?

As you can see I don’t completely dominate all the material about it, this is a company without resources that now is trying to migrate stuff since Cisco servers are slowly dying.

Thanks in advance to anyone.

Sorry, not familiar with Issabel.

Another thought:
Is anyone still using wired phones? Maybe it’s time to transition to audio/video streaming (Teams, Zoom, etc.) instead of investing in phone technology.
I haven’t used a wired phone in years… just saying.
