Version 6.2 865 February 2011
SIP User's Manual 12. Configuration Parameters Reference
Parameter Description
DSP allocation. SRTP to SRTP does not require DSP
allocation.
Note: This parameter can only be configured as an IP Profile,
using the IPProfile parameter (see ''Configuring IP Profiles''
on page 143).
[SBCRFC2833Behavior]
Determines RFC 2833 SDP offer\answer negotiation.
[0] As is = The device does not intervene in the RFC 2833
negotiation. (default)
[1] Extend = Each outgoing offer\answer includes RFC
2833 in the offered SDP (the device adds RFC 2833 only
if the incoming offer does not include RFC 2833).
[2] Disallow = The device removes RFC 2833 from the
incoming offer.
Note: This parameter can only be configured as an IP Profile,
using the IPProfile parameter (see Configuring IP Profiles on
page 143).
[SBCAlternativeDTMFMethod]
The device's first priority for DTMF method at each leg is
RFC 2833. Therefore, if a specific leg negotiates RFC 2833
successfully, then the chosen DTMF method for this leg is
RFC 2833. For legs where RFC 2833 is not negotiated
successfully, the device uses this parameter to determine the
chosen DTMF method for the leg.
[0] = Don’t care - the device does not attempt to interwork
any special DTMF method. (default)
[1] = In Band
[2] = INFO, Cisco
[3] = INFO, Nortel
[4] = INFO, Korea
Note: This parameter can only be configured as an IP Profile,
using the IPProfile parameter (see Configuring IP Profiles on
page 143).
Web: Diversion Mode
[SBCDiversionMode]
Defines the device’s handling of the SIP Diversion header.
For a detailed description of the device's interworking of the
History-Info and Diversion headers, see ''Interworking SIP
Diversion and History-Info Headers'' on page 505.
[0] Don't Care = Diversion header is not handled. (default)
[1] Add = History-Info header converted to a Diversion
header.
[2] Remove = Removes the Diversion header and the
conversion to the History-Info header depends on the
settings of the SBCHistoryInfoMode parameter.
Note: This parameter can only be configured as an IP Profile,
using the IPProfile parameter (see ''Configuring IP Profiles''
on page 143).
Web: History Info Mode
[SBCHistoryInfoMode]
Defines the device’s handling of the History-Info header. For
a detailed description of the device's interworking of the
History-Info and Diversion headers, see ''Interworking SIP
Diversion and History-Info Headers'' on page 505.
