Hi Harikrish 
 
This sounds related to the SIP helper, given this traffic is being sent over a VPN, does disabling the SIP helper improve the situation? This can be done by running the following from the Console prompt: 
 
console> cyberoam system_modules sip unload 
 
(This can be re-enabled again using the "cyberoam system_modules sip load" command)

HI , 
 
 some time when even tunnel is up and you can ping machines behind either side of firewall but voice or some other traffic may not pass . in such a case you have to check your vpn policy if it is not matching completely such a issue may occur.
