I think you might be better off with standard NAT-handling functions
from nathelper module, i.e. fix_nated_contact()

Hi Ricardo ,
I too need the same process which you had done by subst();
function. two weeks back i had posted a mail to ser-users . regarding
this issue.
because one call-shop with the small sip-proxy using private
ip-adress controls the remaing phones . and with one username i am
giving access to all phones so that i can bill for one account only .
but when a sip-phone registered to that callshop make call it
forwards to my SER with contact id
as eg: 12345(a)192.168.2.101 <mailto:12345@192.168.2.101> .so, the call
comes in as it just requires authorise but when we hung the phone the
"BYE" messages are not recieving by both end parties because SER is
sending "BYE" messages to that contact-id that is private ip so call
became "idle" for 30-40 seconds and after it shut down.
so now i need to rewrite the contact part of that private ip-address
and just use NAT ipadress
of that sip-proxy(call-shop)
i saw your subst(); funct. in your mail but i dont know where and how
to use that,(I am not a programmer)
So how you suggest me to do that for rewriting any private
ip-adresss and replacing NAT-address so that the call will ends when
it recieve "BYE" message .
below is the trace of that:
