Table 7: Session Expiration Settings Parameters


A SIP Extension to notify the SIP server that the phone is behind a NAT/Firewall. Do not configure this parameter unless this feature is supported on the SIP server.

Outbound Proxy

Configures the IP address or Domain name of the Primary Outbound Proxy, Media Gateway, or Session Border Controller.

Secondary Outbound Proxy

Configures the IP address or Domain name of the Secondary Outbound Proxy, Media Gateway, or Session Border Controller. Secondary outbound proxy will be used when the primary outbound proxy fails.

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.

DNS Mode

Controls how the search appliance looks up IP addresses for hostnames. There are three modes: A Record, SRV, NAPTR/SRV. The default setting is “A Record”. If the user wishes to locate the server by DNS SRV, the user may select “SRV” or “NATPTR/SRV”.

Table 8: Account Settings – Network Settings Parameters


Users can choose different ringtones.

Specifies the mechanism to transmit DTMF digits. 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). The vocoders in the list is a higher preference. Users can configure vocoders in a preference list that is included with the same preference order in SDP message.

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.

H.264 Payload Type

Configures the H.264 codec payload type. The valid range is from 96 to 127.

The default value is 99.


Configures the SRTP Mode, when set to “Enable and Force” it will enable and force to use SRTP and when set to: “Enable but Not Force”, it will enable but not force to use SRTP. The default setting is “Disable”.

Enable SRTP Key Life Time

It is used to configure whether to enable SRTP key life time. If enabled, the RTP packets received and sent during the call cannot exceed 231. The default setting is “Yes”.

Local RTP Port

Defines the local RTP-RTCP port pair used to listen and transmit.

If it is configured with X, in channel 0 the port X will be used for audio RTP message, the port X+1 for audio RTCP message, the port X+2 for video RTP message and the port X+3 for video RTCP. In Channel 1, each port number will be incremented by 4 for each message. This increment rule will apply to other channels and other port numbers.

By default, the Account 1 will use Channel 0, Account 2 Channel 1,

Account 3 Channel 2, Account 4 Channel 3, and Account 5 Channel 4 and Account 6 Channel 5.

If an account needs to establish multiple session simultaneously, the system will use the ports in the next available channels.

The default value is 5004. The valid range is from 1024 to 65400.
