5.12.4 Unnamed words

Unnamed word 15, SIP local RTP port base
By default, the AS55X uses RTP port numbers beginning from 30000. If there should
be a conflict e.g. due to port forwarding in the router, this port number base can be
changed.
Default value: 30000

Unnamed Word 16 to 18, Ethernet MAC address overrun
Default value: 0, factory setting

Unnamed word 19, SIP REGISTER repetition period
If the AS55X is in SIP client mode, after the time value set here, the registration
process at its server will be repeated. Set this value in seconds.
Default value: 300 (5 minutes)

Unnamed word 20, SIP OPTIONS repetition period
The AS55X periodically sends an OPTIONs message, the period length can be changed
here. In SIP peer mode, the sending begins immediately after start-up, in SIP client
mode after successful registration at the server. In SIP server mode the AS55X sends
this message to every registered client. The OPTIONs message can be used as keep
alive function for NAT router entries. Set this value in 10 milliseconds, a period time
of 0 will suppress the OPTIONs sending. The response from the endpoint can be
ignored, even if it is negative.
Default value: 1000 (10 seconds)

Unnamed word 21, service port
This is the listen port for service access via LAN. The default port is 29999 (TCP).
Default value: 0 (same as 29999)

Unnamed word 22, jitter buffer initial delay
If the jitter in a network should be very high, the adaptation can result in some audio
disturbance of VoIP connections. Before increasing this value in bad audio cases, it
should be evaluated with a network protocol tester, if the jitter is really the cause.
This value is understood in ms, the allowed range is 20 to 250.
Default value: 0 (same as 50 ms)
