VoIP Setup Fields
RTP Baseport - Defines the base UDP port to be used when allocating ports for transmitting
or receiving RTP packet streams in VoIP calls. Range is from 1025 - 65535, default is 30000.
RTCP CNAME - Defines the name to be used for the CNAME file of Real-Time Control
Protocol (RTCP) packets.
- To use the Gateway ID in the CNAME.
- Identifies the gateway, maximum of 63 characters.
SDP Address - Defines the Session Description Interval.
- Use the CMG IP address.
- Use the following address.
- Use the MGCP gateway ID.
- Use the DNS domain name id DNS is enabled or CMG IP address if DNS is
disabled.
RTCP Interval(s) - Defines the time interval between RTCP reports. Interval time is in seconds,
range is 0 to 255. If zero, RTCP reporting time is turned off. Default is 5 seconds.
Jitterbuffer Mode - Sets the dynamic delay adjustment to minimize delay through the jitter
buffer, or maintain a static average delay through the jitter buffer.
- Perform dynamic delay adjustment to minimize delay.
- Maintain a static average delay, equal to two times the packet time (default).
Hookflash Timeout (ms) - Defines the flash maximum time in milliseconds. This is the time
beyond which a disconnect, rather than a hookflash event, is declared. The default hookflash time is
1500 milliseconds. Range is between 500 and 1500 milliseconds or 0. Flash event processing may be
turned off by setting this parameter to zero.
Compander - Defines the companding algorithm to use with the PCM (G.711) voice stream
to/from the TDM side of a connection. The default companding algorithm is mu-law. The
companding algorithm chosen for the CMG must match the companding used on the associated
TDM-side connected interface channel, i.e. FXS ports and/or T1/E1 channels.
- The companding algorithm used in Europe and elsewhere.
- The companding algorithm used in North America.
Call Detail Record
- Disables call detail recording.
- Enables call detail recording.
OSI Interval (ms) - Defines the OSI wink time. Range is 500 to 2500, with a default of 900 ms.
Payload Type Processing - Allows the unit to exchange RTP with non-specification compliant
gateways.
- Allows non-spec gateways.
- Does not allow non-spec gateways (default).
