| Description | This object specifies the protocol version
used by the gateway in the messages to MGC
in order to exchange the service capabilities.
For example cmgwSignalProtocol is 'h248(3)' and
this object can be string '1' or '1.0', '2' or '2.0'.
'MAX' is a special string indicating the gateway will
use the highest protocol version supported in the
gateway, but it can be changed to lower version after
it negotiates with MGC. The final negotiated protocol
version will be indicated in cmgwSignalProtocolVersion.
The version strings other than 'MAX' can be specified for
the gateway to communicate with the MGC which doesn't
support service capabilities negotiation. For example if
a MGC supports only version 1.0 MGCP, this object should
be set to '1' to instruct the gateway using MGCP
version 1.0 format messages to communicate with MGC. |
