NAT Traversal	Enables or disables the NAT traversal mechanism. The default setting is “Keep-alive”. If set to “STUN” and STUN server is configured, the phone will route according to the STUN server; If NAT type is Full Cone, Address-Restricted Cone or Port-Restricted Cone, the phone will try to use public IP addresses and port number in all the SIP&SDP messages. The phone will send empty SDP packet to the SIP server periodically to keep the NAT port open if it is configured to be “Keep-alive”. Configure this to be “NAT NO” if an outbound proxy is used. Configure this to be “UPnP” if the router supports UPnP. If set to “Auto”, the phone will try to use all traversal methods mentioned above until find the available one.

There are 3 supported modes: In audio: which means DTMF is combined in the audio signal (not very reliable with low-bit-rate codecs); RTP (RFC2833): permits to specify DTMF with RTP packet. Users could know the packet is DTMF in the RTP header as well as the type of DTMF; SIP INFO: uses SIP INFO to carry DTMF. The defect of this mode is that it’s easily to cause desynchronized of DTMF and media packet for the reason the SIP and RTP are transmitted respectively. Default settings is via “RFC2833”.
Preferred Vocoder	Selects which codecs will be used on Wi-Fi, 2G, 3G and 4G Multiple vocoder types are supported on the phone (PCMU, PCMA, OPUS, G722, G726_32, iLBC, G729 and GSM).

It is recommended to increase the bit rate if the bandwidth is sufficient, and the video quality will be reduced if the bandwidth is not enough. For Wi-Fi network, the default setting is 512kbps; For 2G/3G/4G network, the default setting is 192kbps.
SDP Bandwidth Attribute	Select the SDP bandwidth attribute from “Standard”,” Media Level”,” Session Level” or “None”. • Standard: Use AS at the session level and TIAS at the media level. • Media Level: Use AS at the media level. This is the default setting. • Session Level: Use AS at the session level. • None: Don not change the format. Please do not change the format or it may cause decode failure if unclear about what format the server supports.
