ECOTEL 3G 16.1. Revised: 2011.
VoipPCMPacketInterval=<int>
This parameter changes the default interval for PCM codecs (G.711, G.726). That means the
VoipTxm fac-
tor is muliplied using this interval:
0 = 10ms (default))
1 = 5 ms
2 = 10 ms
3 = 20 ms
VoipCallGroup=<name>
All outgoing VoIP calls for VoIP profiles with the same
VoipCallGroup name are distributed cyclically to
these profiles.
VoipOverflow=<name>
When the value entered in
VoipMaxChan is reached, all overflow calls will be sent to the profile defined
here. An alternative VoIP profile can also be used if the default profile can no longer be used as a result of
poor quality.
VoipDJBufMinDelay=<count>
Enter a value in milliseconds (0-320) to set a minimum jitter buffer limit (default 35). For fax transmission
(t.38) it is fixed to 200ms.
NOTE:
VoipDJBufMaxDelay must be greater than VoipDJBufMinDelay.
VoipDJBufMaxDelay=<count>
Enter a value in milliseconds (0-320) to set a maximum jitter buffer limit (default 150). For fax transmission
(t.38) it is fixed to 200ms.
NOTE:
VoipDJBufMaxDelay must be greater than VoipDJBufMinDelay.
VoipDJBufOptFactor=<count>
Enter a value between 0 and 13 to set the balance between low frame erasure rates and low delay (default
7).
VoipConnBrokenTimeout=<sec>
An entry is generated in the
protocol.log file and the connection is terminated after a connection bro-
ken exists for the number of seconds entered (default 300). If
0 is entered, no entry will be generated and
the connection will not be terminated.
VoipTcpKeepAlive=<mode>
Enter
yes (default) to send the RoundTripDelayRequest message every 10 seconds (necessary for
long calls with firewalls using TCP aging).
VoipIntrastar=<mode>
Enter
Yes to activate the IntraSTAR feature. When the IP connection results in poor quality, an ISDN call is
sent to the peer and the voice data is automatically transmitted via ISDN.
