H.323 Stack Configuration
Note The Q.931 parameter overlappedSending has been combined with the RAS overlappedSending
parameter. If you set the Q.931 overlappedSending parameter, you also set the RAS overlappedSending
parameter.
RAS Parameters
The parameters in Table 3-8 are required for RAS stack initialization. To modify the RAS parameters,
use the ras MML name variable for the prov-add, prov-dlt, and prov-ed commands.
In the following example, the prov-add command sets the RAS parameter maxfail to the value 3.
Example
prov-add:name=ras,maxfail=3
The array index [i] in some of the parameter names in the first column of Table 3-8 must be replaced
with a valid braced index from 1 to 20, and must be continuous and unique (that is, it must contain no
duplicates).
The Update Type column in Table 3-8 shows when the change to a parameter takes effect after it is
modified:
• Immediate means that the effect of the change is immediate.
• Start means that the application needs to be restarted for the change to take effect.
• Next Call means that the next call has the new parameter set.
Table 3-7 Q.931 Parameters
Parameter Name Description Type Example Update Type
responseTimeOut* The maximum time (in seconds) permitted
to receive the first response to a call. If this
parameter expires, the call is disconnected.
INTEGER(1,200) 20 Immediate
connectTimeOut* The maximum time (in seconds) the stack
waits for call establishment after the first
response is received. If this parameter
expires, the call is disconnected.
INTEGER(1,20000) 180 Immediate
callSignalingPort* The number of the port receiving the calls
destined for the PGW 2200.
INTEGER(0,65535) 1720 Start
maxCalls* The maximum number of simultaneous
calls permitted. If this parameter is
exceeded, the next call attempt returns busy.
INTEGER(0,65535) 2500 Next Call
notEstablishControl The stack does not allow the switching of
control from the Q.931 to the H.245 stack.
NULL Not present Next Call
overlappedSending Because the Q.931 configuration flag
indicates that both parties support overlap
sending, this state notifies the other party
that it can send an overlap sending message.
NULL Present Immediate
