Re: [Asterisk-Users] SIP Extension behind NAT, Asterisk on a public domain

[Bharath Khambadkone]

By default AMP had NAT=yes in sip.conf, I read in some posts to change
it to one, i was just trying my luck if that works. I have tried
NAT=yes, The Phone gets registered, I can also make  recieve calls
but as soon as the call is picked I dont hear anything at both ends.
Does this have anything to do with codecs?

[Asterisk-Users] SIP Extension behind NAT, Asterisk on a public domain

[Bharath Khambadkone]

Hello All,
I'm fairly new to asterisk. I have read about the problems about NAT, But can't seem to find a solution.
My Asterisk is on a public domain, there is no NAT or firewall in front
of the asteris box. I have sucessfully connected iax2 softphones 
was able to recieve  make calls. In the same locations where I
have the iax2 extensions working I have set up a a SIP softphone 
a SIP ATA (Sipura2002). Both teh sip phones are able to register. I can
also make  recieve calls but cannot hear anything after the call
is answered at both ends. I'm not sure what is causing this problem. By
the way I'm using SME server 7(centos 4.2) with [EMAIL PROTECTED] installed. 

my Sip.conf :
[2008] ;(Sipura2002)
username=2008
type=friend
secret=2008
record_out=Adhoc
record_in=Adhoc
qualify=no
port=5060
nat=1
[EMAIL PROTECTED]
host=dynamic
dtmfmode=rfc2833
context=from-internal
canreinvite=no
callerid=device 2008


[2009] ;X-Lite Soft Phone
username=2009
type=friend
secret=2009
record_out=Adhoc
record_in=Adhoc
qualify=no
port=5060
nat=1
[EMAIL PROTECTED]

Thanks in advance..
