Why is there no ring back tone?
Sometimes users would encounter this situation: after dialing the LCD displays shows that the call is connecting but you cannot hear the ring back tone. This can be caused by several factors: (1) The network that the phone is in is not functional, and cannot send out the request to the server correctly. Please check the network settings in this case. For example, check if the network cable is securely connected and if there is a problem with the router. (2) The callee is not connected to the network. If you are using the IPVideoTalk server, please do not hang up. The server will transfer the call to the voice/video mail box and you can leave a message for the callee. When the callee connects back to the server, a notification will be sent out to the callee to retrieve the message. (3) The server registered is not functional and ignores all the requests by the phone. Please contact the service provider for more assistance in this case.

Will the GXV3500 Decoder/Encoder be compatible with third party cameras?
Encode Mode: (Analogue Camera) Generally, most 3rd party analogue cameras will be digitized to IP Camera when connecting to GXV3500 BNC port at Encode Mode. Decode Mode: (IP Camera) Whether GXV3500 can decode the data stream from a 3rd party IP camera is dependent on how the stream was encoded. GXV3500 utilizes the RTSP stream and is capable ONLY H.264 formats decoding (so MJPEG is out of luck). General rule of thumb is if the RTSP stream of 3rd party IP Camera can be viewed by VLC Player (free open source media player software), the GXV3500 will very likely be able to decode the stream, but no guarantee due to the variety of H.264 encoding implementation by different IP Camera vendors.
