Parameter  Description 
configure voip > gateway voice-mail-
setting > smdi-timeout-[msec] 
[SMDITimeOut] 
Call Status message before or after a Setup message is 
received. The parameter synchronizes the SMDI and analog 
CAS interfaces. 
If the timeout expires and only an SMDI message is 
received, the SMDI message is dropped. If the timeout 
expires and only a Setup message is received, the call is 
established. 
The valid range is 0 to 10000 (i.e., 10 seconds). The default  
is 2000.

configure voip > gateway voice-mail-
setting > mwi-off-dig-ptrn 
[MWIOffCode] 
Defines the digit code used by the device to notify the PBX 
that there are no messages waiting for a specific extension. 
This code is added as prefix to the dialed number. 
The valid range is a 25-character string. 
MWI On Digit Pattern 
configure voip > gateway voice-mail-
setting > mwi-on-dig-ptrn 
[MWIOnCode] 
Defines the digit code used by the device to notify the PBX 
of messages waiting for a specific extension. This code is 
added as prefix to the dialed number. 
The valid range is a 25-character string. 
MWI Suffix Pattern 
configure voip > gateway voice-mail-
setting > mwi-suffix-pattern 
[MWISuffixCode] 
Defines the digit code used by the device as a suffix for 
'MWI On 
Digit Pattern' and 'MWI Off Digit Pattern'. This suffix 
is added to the generated DTMF string after the extension 
number.  
The valid range is a 25-character string.
 
MWI Source Number 
configure voip > gateway voice-mail-
setting > mwi-source-number 
[MWISourceNumber] 
Defines the calling party's phone number used in the Q.931 
MWI Setup message to PSTN. If not configured, the 
channel's phone number is used as the calling number. 
configure voip > gateway dtmf-supp-
service supp-service-settings > mwi-
subs-ipgrpid 
[MWISubscribeIPGroupID] 
Defines the IP Group ID used when subscribing to an MWI 
server. The 'The SIP Group Name' field value of the IP 
Groups table is used as the Request-URI host name in the 
outgoing MWI SIP SUBSCRIBE message. The request is 
sent to the IP address defined for the Proxy Set that is 
associated with the IP Group. The Proxy Set's capabilities 
such as proxy redundancy and load balancing are also 
applied to the message. 
For example, if the 'SIP Group Name' field of the IP Group is 
set to "company.com", the device sends the following 
SUBSCRIBE message:  
SUBSCRIBE sip:company.com...   
Instead of:   
SUBSCRIBE sip:10.33.10.10... 
Note: If the parameter is not configured, the MWI 
SUBSCRIBE message is sent to the MWI server as defined 
by the MWIServerIP parameter. 
[NotificationIPGroupID]  Defines the IP Group ID to which the device sends SIP 
NOTIFY MWI messages.
