I have a problem between the configuration for pickup in my server PBX and the voip analog gateway. When I press "#0" on an analog phone, it should pick up the call from another phone that is ringing in that moment, as it's setting in the server PBX. But, nothing happens, The phone cannot answer the call. I checked "basic preferences" and I disabled the option "key as send" because i don't want to match the "#" between gateway and server when the user press "#" to make a call after dial the number. I comment that the server is not Yeastar and I think this makes me have the issue but, I need to figure out.
