[Freeswitch-users] Call drops after few minutes

[Rajil Saraswat]

Hello,

I have a sip client (Android Csipsimple) connected to my FS server.
Any outbound calls i make drop after some time. The FS server is
running in a FreeBSD jail on a separate network (192.168.10.10) to the
Android phone which is on a LAN (172.16.1.21).

I have the following acl defined.

        <list name="natme" default="allow">
                <node type="deny" cidr="192.168.10.0/24"/>
                <node type="deny" cidr="172.16.1.0/24"/>
        </list>

        <list name="nonat" default="deny">
                <node type="allow" cidr="192.168.10.0/24"/>
                <node type="allow" cidr="172.16.1.0/24"/>
        </list>

In internal profile (internal.xml) the acl is setup as

                <param name="apply-nat-acl" value="natme"/>
                <param name="local-network-acl" value="nonat"/>

Following is the wire-shark representation of the call. Any idea what
my call is being dropped?
