Hi I have a grandstream gxp-2000 and trying it on an asterisk 1.6. When I call internally between extensions I can hear the other person in the gxp2000, but when I call externally from the gxp I can't hear the person on the other end, but he can hear me. How do you configure the grandstream 2000 to work on asterisk 1.6?

Is it VoIP, PSTN, or ... ? If it's VoIP then it's almost certian to be a NAT problem with your network/router. There's no magic in setting up GXP2000's - they're fairly straightforward, and if you can do phone to phone, (via an asterisk) they're probably OK. Let us know more about the external connection technology... Gordon
