Hello,

i've recently configured my asterisk for internal sip calls.
while testing, i noticed that 1 out of 10 calls works..
at first i thought my router dropping packets around the way as it were a bottle neck..
so i've added a switch.

once i tested again same prob occurs...

im using xlite as a softphone on clients pc
and centos server on a dedicated machine.

at times the phone call goes through and voice is perfect..
and at others one side can hear me yet i cant hear them.. and at others neither one of us can hear the other end..

i've checked my logs and havent found anything relevant.. but yet again maybe you could as i'm a newbie..
