[Freeswitch-users] OpenZap Not working Stable

[palani sivagurunathan]

Hi,

    I have installed freeswitch through SVN in centos.OutBound is working
fine .But not always .Once we make 8 to 10 call from a sip extension we get
service unavailable error in xlite . Error and configuration are  pasted
below .we observed the problem is getting rectified after 5 to 10 mins .and
we are able to make calls and again after 8 to 10 calls Errors  happen

how to check. what will be the issue
