Valid Range and Description
PlayRBTone2IP
[Play Ringback Tone to IP]
0 = Ringback tone isn’t played (default).
1 = Ringback tone is played (to IP) after SIP 183 session progress response is
sent.
If configured to ‘1’ (Play),
For IP
Æ
Tel calls, if a Progress or an Alert message with PI is sent from the
ISDN and ‘EnableEarlyMedia = 1’, the V7122 opens a voice channel and
sends 183 response. It doesn’t play a Ringback tone to IP (assuming that the
Ringback tone is played by the ISDN).
Otherwise, if a voice channel isn’t opened, the V7122 plays Ringback tone to
IP, after receiving an Alert message from the ISDN. It sends 183 response,
signaling the originating party to open a voice channel in order to hear the
played Ringback tone.
To enable the gateway to send a 183 response, set
‘EnableEarlyMedia’ to 1.
If ‘EnableDigitDelivery = 1’, the gateway doesn’t play a Ringback
tone to IP and doesn’t send a 183 response.
DefaultCauseMapISDN2I
P
[Default Cause Mapping
From ISDN to IP]
Defines a single default ISDN Release Cause that is used (in ISDN to IP calls)
instead of all received release causes except when the following Q.931 cause
values are received: Normal Call Clearing (16), User Busy (17), No User
Responding (18) or No Answer from User (19).
The range is valid Q.931 release causes (0 to 127). The default value is 0
(indicates that the parameter is not configured - static mapping is used).
CauseMapSIP2ISDN_ID
[Release Cause Mapping
from SIP to ISDN]
Defines a flexible mapping of SIP Responses and Q.850 Release Causes.
CauseMapSIP2ISDN_<ID> = <SIP Response>,<Q.850 Release Cause>
When a SIP response is received (from the IP side), the gateway searches this
mapping table for a match. If the SIP response is found, the Release Cause
assigned to it is sent to the PSTN. If no match is found, the default static
mapping is used.
For example:
CauseMapSIP2ISDN=404,3
This parameter can appear up to 12 times.
CauseMapISDN2SIP_ID
[Release Cause Mapping
from ISDN to SIP]
Defines a flexible mapping of Q.850 Release Causes and SIP Responses.
CauseMapISDN2SIP_<ID> = <Q.850 Release Cause>,<SIP Response>
When a Release Cause is received (from the PSTN side), the gateway
searches this mapping table for a match. If the Q.850 Release Cause is found,
the SIP response assigned to it is sent to the IP side. If no match is found, the
default static mapping is used.
For example:
CauseMapISDN2SIP=6,406
This parameter can appear up to 12 times.
