Preferred Minimum Session Refresh Interval (sec)
Appears when Group Type is sip, and SCCAN is n. This field sets the session refresh timer
value of an SES session for non-SCCAN applications. The timer starts once an SES session
established. Avaya Communication Manager then sends a session refresh request as a
Re-INVITE or UPDATE after every timer interval. In this way, an ongoing session is maintained.
If a session refresh request is not received before the interval passes, the session terminates.
Valid entries
90 to 1800
Usage
Enter tone to use Dual Tone Multifrequency (DTMF) addressing, also
known as "touchtone" in the U.S. Entering tone actually allows the trunk
group to support both DTMF and rotary signals.
For pulsed and continuous E&M signaling in Brazil and for discontinuous
E&M signaling in Hungary, use tone or mf.
Enter rotary if you only want to allow the dial pulse addressing method
used by non-touch tone telephones. If you have a full touch tone system
internally and a connection to a central office that only supports rotary
dialing, for example, it would be appropriate to enter rotary.
Enter r1mf for CAMA trunk groups. It is the only outgoing dial type
allowed on CAMA trunk groups.
Enter r1mf to allow Russian MF Packet Signaling on outgoing trunks.
Russian MF Packet Signaling carries calling party number and dialed
number information. Group type field must be set to co.
Enter mf if the Trunk Signaling Type field is blank. The Multifrequency
Signaling field must be enabled on the System-Parameters
Customer-Options screen in order for you to enter mf here.
You cannot enter mf if the Used for DCS field (Field descriptions for page
2) is y.
For pulsed and continuous E&M signaling in Brazil and for discontinuous
E&M signaling in Hungary, use tone or mf.
Enter automatic for tie trunks if the Trunk Signaling Type field is blank.
This provides "cut-through" operation to outgoing callers who dial a trunk
access code, connecting them directly to central office dial tone and
bypassing any toll restrictions administered on Communication Manager.
Usage
Administer the desired number of seconds for the session refresh interval.
Default is 120.
