How did you configure the trunk between the 2 servers?
using register => user:pass at external server
or using extension?

Host                      Username        Perceived                 Refresh      State

 IAX_DEFAULT_REG_EXPIRE

that is the value to be       changed in iax2.h

Hi,         

I have successfully         configured an IAX trunk between 2 asterisks, calls can go through both         ways without any problems, NAT in the middle of course         (iptables)

Now , leave them for a while         ,   and make a call from the external server , it doesnt go         through, 

Dial from the internal one,         everything works fine again..

Now , it is clearly  a         problem in the NAT engine, although IAX shouldnt have this         problem    

is there something I can do         to prevent asterisk from tearing down the trunk while it is not         used

or , modify the iptables so         that  to allow the incoming UDP         connections

Cheers
