Disable All SCTP Transport for SIP Packet Trunking
....................................................................................................................................................................................................................................
Purpose
This procedure prevents new incoming or outgoing SIP calls from
being established over the SCTP transport layer.
With all associations removed from service (in the CLOSED MAN
state), far offices should mark all SIP packet groups to this office as
out-of-service, and incoming SIP call attempts should cease.
When to use
This procedure should only be used to prevent any incoming or
outgoing calls from using SIP packet trunking with SCTP transport,
generally only if the whole SIP packet trunking feature is being
degrown from the office.

the RC/V system.
Refer to the 235-600-700/750, Input/Output Messages manuals for
additional information on the Input and Output commands.
Admonishments
• If there is no equivalent circuit route (such as an ISUP7 trunk
group) to a particular far office that is served by SIP packet
trunking, this procedure will cause it to be impossible to route
calls to that far office.
• If an SM Full Initialization of a SIP GSM occurs, the effects of
this procedure are automatically reversed by the initialization,
and this procedure will need to be repeated.
