Hey everyone, I work for a phone and internet company that's looking to integrate our phones with Zoho. We have physical phones and a softphone that is connected to it

Currently our only goal is click-to-dial

I've looked through the documentation of PhoneBridge, and there does not seem to be a way to enter custom credentials, so I'm assuming that PhoneBridge is a feature to specifically connect those PBXs (Twilio, Asterisk, etc) 

Is there another way to set up click to dial with existing phones? I've seen some doing it with Skype
