[. . . ] e. g. , if the first codec is configured as G723 and the "Voice Frames per TX" is set to be 2, then the "ptime" value in the SDP message of an INVITE request will be 60ms because each G723 voice frame contains 30ms of audio. Similarly, if this field is set to be 2 and if the first codec chosen is G729 or G711 or G726, then the "ptime" value in the SDP message of an INVITE request will be 20ms. If the configured voice frames per TX exceeds the maximum allowed value, the HandyTone ATA will use and save the maximum allowed value for the corresponding first codec choice. The maximum value for PCM is 10(x10ms) frames. And 32 (x30ms) and 64 (x10ms) frames for G723 and G729 respectively. T. 38 (Auto Detect) FoIP by default, or Fax Pass-Through. This field defines the layer 3 QoS parameter which can be the value used for IP Precedence or Diff-Serv or MPLS. VLAN supported equipment is required if user needs to change these settings. Layer 2 QoS settings for LAN port device traffic. VLAN supported equipment is required if user needs to change these settings. Fax Mode Layer 3 QoS Layer 2 QoS ( VoIP) Layer 2 QoS ( PC) Allow incoming SIP If set to "Yes", the device will ignore any SIP message that does not come from messages from SIP the IP address (Source IP in the IP header) that it is registered to. proxy only Use DNS SRV: User ID is Phone Number SIP Registration Unregister on Reboot Default is "No". If set to "Yes" the client will use DNS SRV to lookup for the server. If set to yes, a "user=phone" parameter will be attached to the "From" header in SIP request. This parameter decides whether the HandyTone ATA needs to send REGISTER messages to the proxy server. If set to "Yes", the device will first send registration request to remove previous bindings. Register Expiration This parameter allows the user to specify the time frequency (in minutes) the HandyTone ATA will refresh its registration with the specified registrar. The default interval is 60 minutes (or 1 hour). The maximum interval is 65535 minutes (about 45 days). 30 HandyTone-486 User Manual Grandstream Networks, Inc. Early Dial Allow outgoing call without Registration Dial Plan Prefix No Key Entry timeout Use # as Send Key Default is "No". Use only if proxy supports 484 response. When set to "Yes", the device still has a dial tone and allows user make outgoing calls even if the device is not registered to the SIP proxy. Sets the prefix added to each dialed number. This parameter allows user to configure the "#" key to be used as the "Send" (or "Dial") key. [. . . ] It is used periodically to transmit control packets to participants in a streaming multimedia session. The primary function of RTCP is to provide feedback on the quality of service being provided by RTP. RTP Real-time Transport Protocol defines a standardized packet format for delivering audio and video over the Internet. It was developed by the Audio-Video Transport Working Group of the IETF and first published in 1996 as RFC 1889 SDP Session Description Protocol, is a format for describing streaming media initialization parameters.
