I'm new with the 3CX Phone System, I've found it when I was searching for a free standalone PBX. Our company has POLYCOM SoundPoint IP 320 SIP IP Phones and I tried one of it on 3CX Gateway for Skype where I can use the IP Phone as my incoming call device through 3CX Phone System. We are planning to use our IP Phones to connect and make calls on Skype through Skype Manager's Skype Connect (SIP). As instructed by Skype, we need to register the Skype SIP Profile on our PBX, the problem is, we never had the access on our main PBX device. The question is, can we use the 3CX Phone System for registering those Skype SIP Profiles on the PBX itself? The Skype SIP's address is sip.skype.com, where should I put this address up? I configured the 3CX Gateway for Skype on PSTN devices, how about the Skype SIP? When I created the Skype SIP Profile, they gave me 2 option on registering the Profile to the PBX, I'd rather choose IP Authentication method as I think it is much easier. I just typed down the Public IP Address of my 3CX Phone System. After that, Skype gave my details to configure the PBX: Skype Connect addresses Primary - 2.sip.skype.com (126.96.36.199) Secondary - 1.sip.skype.com (188.8.131.52) Where am I going to set this SIP address up on my 3CX Phone System? Any help will be much appreciated. Thanks!
