5 Additional VoIP parameters
Table 5.3 Customized parameters: SIP signaling (page 2 of 4)
SIP Signaling Parameters
VoipContact=<account@domain> | <ip address> | RH
Used for the Contact field in Sip-Invite and Sip-Response messages. Can be entered in
the parameter or, with the RH keyword, taken from the request header of the incom-
ing SIP-Invite.
VoipContactParam=<string>
Sets additional header parameters in the contact field.
VoipDadSource=<int>
SIP only: defines the field from which field the called party number coming from SIP
is to be taken:
0 = URL or URI in the Invite request that contains only digits, otherwise the To: field is
used (default)
1 = To: field
2 = Remote-Party-ID with party = called
4 = URL or URI in the Invite request that can also contain letters
8 = Diversion header (in case a redirect number is to be used as destination number)
VoipDelayDisc=<mode>
Yes delays confirmation transmission during call teardown. That means the release
tone is audible when the peer tears down the call. Default is no.
VoipInfoSamOnly=<mode>
This parameter determines the behavior in the case of overlap sending (VoipOverlap
must also be set). Yes means that the contents of the SubsequentNumber field in info
method will be attached to the URI's available digits or to the invite message's To field.
No (default) means that the digit contents of the SubsequentNumber field will be
used.
VoipOadSource=<int>
SIP only: defines the field from which field the calling party number coming from SIP
is to be taken:
0 = From: field (default)
1 = Remote-Party-ID
2 = P-Preferred-Identity
4 = P-Asserted-Identity
8= Display field
NOTE: If 2 or 4 are entered, the number in the field must begin with tel:
Going to SIP, the OAD is written in the following field:
0 = From: field (default)
1 = Remote-Party-ID (if VoipOwnAddress is not set)
For the fields P-Preferred-Identity and P-Asserted-Identity, please check the corre-
sponding parameters. If the number is sent with CLIR to SIP, the From: field contains
anonymous@anonymous.invalid. If the number has to appear in the From: Field, the
decimal value of the parameter must be increased by 8.
VoipOverlap=<mode>
SIP only. Enter yes to activate signaling with overlap sending, as per draft-zhang-sip-
ping-overlap-01.txt. That means digit collection is no longer necessary in the routing
when the digits come from ISDN/POTS with overlap sending. When this parameter is
active, VoipPrack is automatically set to yes. Default is no.
