AudioCodes Mediant 600 - General SIP Parameters

SIP User's Manual 594 Document #: LTRT-83310
Mediant 600 & Mediant 1000
Parameter Description
a. Uses an external STUN server (STUNServerPrimaryIP
parameter) to assign a NAT address for all interfaces.
b. Uses the StaticNATIP parameter to define one NAT IP address
for all interfaces.
c. Uses the NATTranslation parameter to define NAT per interface.
 If NAT is not configured (by any of the above-mentioned methods),
the device sends the packet according to its IP address defined in the
Multiple Interface table.
A.9 General SIP Parameters
The general SIP parameters are described in the table below.
Table A-31: General SIP Parameters
Parameter Description
Web/EMS: Max SIP Message
Length [KB]
[MaxSIPMessageLength]
Defines the maximum size (in Kbytes) for each SIP message that can
be sent over the network. The device rejects messages exceeding
this user-defined size.
The valid value range is 1 to 50. The default is 50.
[SIPForceRport]
Determines whether the device sends SIP responses to the UDP port
from where SIP requests are received even if the 'rport' parameter is
not present in the SIP Via header.
 [0] (default) = Disabled - the device sends the SIP response to the
UDP port defined in the Via header. If the Via header contains the
'rport' parameter, the response is sent to the UDP port from where
the SIP request is received.
 [1] = Enabled - SIP responses are sent to the UDP port from
where SIP requests are received even if the 'rport' parameter is
not present in the Via header.
Web: Max Number of Active
Calls
EMS: Maximum Concurrent
Calls
[MaxActiveCalls]
Defines the maximum number of simultaneous active calls supported
by the device. If the maximum number of calls is reached, new calls
are not established.
The valid range is 1 to the maximum number of supported channels.
The default value is the maximum available channels (i.e., no
restriction on the maximum number of calls).
Web: Number of Calls Limit
[CallLimit]
Defines the maximum number of concurrent calls per IP Profile. If the
IP Profile is set to some limit, the device maintains the number of
concurrent calls (incoming and outgoing) pertaining to the specific
profile. When the number of concurrent calls is equal to the limit, the
device rejects any new incoming and outgoing calls belonging to that
profile.
This parameter can also be set to the following:
 [-1] = There is no limitation on calls for that IP Profile (default).
 [0] = Calls are rejected.
Notes:
 This parameter can only be configured for an IP Profile using the
IPProfile parameter (see 'Configuring IP Profiles' on page 219).
 For IP-to-IP calls, you can configure the device to route calls to an
alternative IP Group when the maximum number of concurrent
calls is reached. To do so, you need to add an alternative routing
