Voice Port for Voice over IP (voip)
Home menu level: /ip telephony voice-port voip
Description
The voip voice ports are virtual ports, which designate a voip channel to another host over the IP
network. You must have at least one voip voice port to be able to make calls to other H.323 devices
over IP network.
Property Description
name ( name ) - name given by the user or the default one
remote-address ( IP address ; default: 0.0.0.0 ) - IP address of the remote party (IP telephone or
gateway) associated with this voice port. If the call has to be performed through this voice port, then
the specified IP address is called. If there is an incoming call from the specified IP address, then the
parameters of this voice port are used. If there is an incoming call from an IP address, which is not
specified in any of the voip voice port records, then the default record is used. If there is no default
record, then default values are used
• 0.0.0.0 - the record with this IP address will specify the default values for an incomming call
autodial ( integer ) - phone number which will be added in front of the telephone number received
over the IP network. In most cases it should be blank
jitter-buffer ( time : 0 ..1000ms ; default: 100ms ) - size of the jitter buffer
• 0 - the size of it is adjusted automatically during the conversation, to keep amount of lost
packets under 1%
silence-detection ( yes | no ; default: no ) - whether silence is detected and no audio data is sent
over the IP network during the silence period
prefered-codec ( name ; default: none ) - the preferred codec to be used for this voip voice port. If
possible, the specified codec will be used
• none - there is no preferred codec defined for this port, so whichever codec advised by the
remote peer will be used (if it is supported)
fast-start ( yes | no ; default: yes ) - allow or disallow the fast start. The fast start allows
establishing the audio connection in a shorter time. However, not all H.323 endpoints support this
feature. Therefore, it should be turned off, if there are problems to establish telephony connection
using the fast start mode
