[Asterisk-Users] DSLink modem freeze

[Andres]

Its probably has a broken ALG (most of these modems have bad SIP 
implementations)  I suggest you change your SER port to a non-standard 
one so that the ALG does not try to modify the packet.  (We had to do 
that a while ago.  Almost 40% of complaints comming in to us stemmed 
from bad SIP ALGs at routers and modems.
