Hello,
I'm trying to connect my IP phone Cisco 7975G to my FreePhoneLine SIP account. I tested the phone and the xml file with another VoIP provider and it works. To connect to FreePhoneLine, I tried many different configuration but nothing works.
Any suggestions as to what configuration needs to be done to get the phone to connect to my SIP account? I have another phone, Linksys SPA942, and it connects to the FreePhoneLine without any issues. The Linksys is turned off while I try to connect the 7975G.
