 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
