Reg Retry Intvl Interval to wait before the PHONE ADAPTER
retries registration again after encountering a
failure condition during last registration
Time0 30
Reg Retry Long
Interval
When Registration fails with a SIP response
code that does no match <Retry Reg RSC>,
the PHONE ADAPTER will wait for the delay
specified in this parameter before retrying. If
this parameter is 0, the PHONE ADAPTER
will stop retrying. This value should be much
larger than <Reg Retry Intvl> which should
not be 0.

RTP Parameters
RTP Port Min
2
Minimum port number for RTP transmission
and reception
Port 16384
RTP Port Max
2
Maximum port number for RTP transmission
and reception
Port 16482
RTP Packet Size Packet size in sec. Valid values must be
multiple of 0.01s. Range: 0.01 – 0.16

RTCP Tx Interval
4
Controls the interval (sec) to send out RTCP
sender report on an active connection.
Range: 0 – 255 (s)
Time0 0
Notes:
1. Reorder or Busy Tone will be played by default for all unsuccessful response status code
2. <RTP Port Min> and <RTP Port Max> should define a range that contains at least 4 even number
ports, such as 100 – 106
3. If inbound SIP requests contain compact headers, PHONE ADAPTER will reuse the same
compact headers when generating the response regardless the settings of the <Use Compact
Header> parameter. If inbound SIP requests contain normal headers, PHONE ADAPTER will
substitute those headers with compact headers (if defined by RFC 261) if <Use Compact
Header> parameter is set to “yes.”
4. During an active connection, the PHONE ADAPTER can be programmed to send out compound
RTCP packet on the connection. Each compound RTP packet except the last one contains a SR
(Sender Report) and a SDES.(Source Description). The last RTCP packet contains an additional
BYE packet. Each SR except the last one contains exactly 1 RR (Receiver Report); the last SR
