under Setup Assistant provides three categories of settings - Account, Server and VoiceMail. Account: Please provide the username and password for the VoIP/SIP account. Also provide the Domain name for the account. The username and Domain are used to construct the SIP URI for the account as in the example below: User name- johndoe Domain- voipservice.sip.com SIP URI- sip:[email protected] The name of the VoIP Service Provider can also be specified; this is optional. Server: This category is for the SIP settings associated with the SIP-enabled IP-PBX or the SIP Server. The name/s or IP Address/es of the SIP Proxy and the SIP Registrar must be specified here. By default, 'Register with SIP Proxy' is checked, indicating that the SIP Proxy is also used as the SIP Registrar. In this case, the name or IP Address of the SIP Proxy only needs to be provided and the same name/IP address is also used for the SIP Registrar. If the Proxy and the Registrar are different, please uncheck 'Register with SIP Proxy' and provide the name/IP address for the SIP Registrar in addition to the SIP Proxy. Voice Mail: If a Voice Mail number is provided with the account, please include it here. This is optional. The 'Options' button can be used to access some advanced VoIP settings. The UDP signaling method can be toggled between symmetric and asymmetric. Symmetric UDP signaling is used by default. An option to enable early UDP packets on RTP and RTCP ports is available. This enables opening of ports on a NAT allowing NAT traversal of traffic. A prefix digit can be added to outgoing phone numbers. For example, if '9' is specified as the prefix digit, it is automatically pre-pended to all 11-digit, 10-digit and 7digit phone numbers. By default, no prefix digit is used. The DSCP field in the IP header of voice packets contains a QoS number that determines the priority voice packets get over data packets in the network. By default, 56 is used as the DSCP QoS number. This can be modified to increase or decrease the priority of voice traffic. Once all the appropriate information is provided, apply the configuration to the phone. If Wi-Fi is on and connected to an AP, the phone will register with the specified SIPenabled IP-PBX or the SIP Server. If Wi-Fi is off, SIP registration will occur when the next time Wi-Fi is turned on and connected to an AP. The status of the 'Internet Calling' plug-in will either be 'Available' or 'Selected'. 'Available' means that the phone has Wi-Fi access and is registered with the IP-PBX, but the next outgoing call will be over cellular. 'Selected' means that the phone has Wi-Fi access, is registered with the IP-PBX
