I have 2 Grandstream GXP2000 phones and a remote user using the Xlite softphone. When calling between the SIP phones, we can’t hear each other. I also have an analog phone plugged into a digium card and if I use it, we can hear each other. Is there something I’m missing in my config to allow SIP to SIP calls?
