.1.3.6.1.4.1.351.150.20.1.1.1 · 1 row entry · 21 columns
Open in standard view 
This table defines attributes used to set up a static
trunked VoIP connection between an endpoint and
another endpoint on a remote VISM. 
          
The maximum number of RTP connections that can be established
is based on the current codec template, which is
vismAppliedTemplate(defined in CISCO-VISM-MODULE-MIB MIB)
object.  
          
Before establishing the connection, endpoints on either
VISM's should have been created and the line signaling
type needs to be configured.
vismRtpConnGrpEntry entry .1.3.6.1.4.1.351.150.20.1.1.1.1
An entry in the vismRtpConnGrpTable.

This table applies to VoIP trunking applications.

The configuration is retained after VISM card reboots.
