[Oreka-user] Clarification on orkaudio config.xml instructions

In the orkaudio config.xml file there is a section that reads:
            <VoIpPlugin>
                        <!-- Use this if you want to force capture from
a given list of devices. -->
                        <!-- All available devices are listed in
orkaudio.log when the service is starting -->
 
<!--<Devices>\Device\NPF_{E0E496FA-DABF-47C1-97C2-DD914DFD3354},
\Device\NPF_{ADE496FA-DABF-47C1-97C2-DD914DFDAB38}</Devices>-->
 
 
<Devices>\Device\NPF_{3B56DD2E-A9A7-4963-A08E-E8F0645F50AB}</Devices>
 
                        <!-- If AllowedIpRanges is used, only packets
with *both* source and destination -->
                        <!-- matching the list are retained -->
                        <!--<AllowedIpRanges>212.125.143.0/24,
82.150.0.0/16, 82.199.64.133</AllowedIpRanges>-->
                        <!-- If BlockedIpRanges is used, packets with
*either* source or destination -->
                        <!-- matching the list are dropped -->
                        <!--<BlockedIpRanges>212.125.143.0/24,
82.150.0.0/16, 82.199.64.133</BlockedIpRanges>-->

                        
                        <!-- LanMasks can be ignored if you have
standard LAN addresses (192.168.x.x or 10.x.x.x) -->
                        <!-- LanMasks might be used to determine the
direction of a call (incoming or outgoing into or from the LAN) -->
                        <!--<LanMasks>10.4.3.4, 1.2.3.4</LanMasks>-->
                        
                        <!-- The following is a csv list of your PBX,
PSTN gateway, conferencing server or such "gateway" devices -->
                        <!-- It is needed to properly detect call
direction -->
                        <!--<MediaGateways>10.0.0.102</MediaGateways>-->
            </VoIpPlugin>
 
Five Questions
1)
This question concerns the parameter <AllowedIpRanges>.
The instructions state if it is used only packets with *both* source and
destination matching the list are retained.
 
Would you please expand upon this instruction?  For example, if orkaudio
is listening on a sip gateway and the internal ip address range is
192.168.0.0/254 and the sip gateway is 789.123.456.1, does this mean
that the parameter <AllowedIpRanges> must be of the following:
 
 <AllowedIpRanges>192.168.0.0/254, 789.123.456.1</AllowedIpRanges>
 
2)
Can the range be in the form 192.168.0/254 or must it be a full list of
192.168.0.0/254, 192.168.1.0/254, etc.?
 
3)
If the calls are coming in from the gateway, does the AllowedIpRanges
required the "outside" address of the sip gateway as well as the
"inside" address?
 
4) 
Is Orkaudio SIP 2.0 compliant?
 
5)
What were the issues you found related to the drop of one side of the
conversation?
 
Thanks,
