Hi,
calls from a UA that is on public ip go through the pstn gw and terminate
ok.
Calls from behind NAT get a 503 error from the GW when the INVITE message is
sent from SER.
The invite messages for both cases are the same except from the VIA header
which for the latter one contains the private ip of the UA.
Contact header is ok.
Could that be the reason that im getting calls rejected?
Is there a way to rewrite the VIA header?
Im including the configuration file i have and some packet dumps of the
calls.Thanks!

Just wanted to add that I also get the warning: I wont send a reply for
ACK.
I guess that means ACK from UA behind NAT dont reach the pstn gw?
thanks,
Kyriakos

Subject: [Serusers] Calls from UAs behind NAT getting a 503 error...
Hi,
calls from a UA that is on public ip go through the pstn gw and terminate
ok.
Calls from behind NAT get a 503 error from the GW when the INVITE message
is sent from SER.
The invite messages for both cases are the same except from the VIA header
which for the latter one contains the private ip of the UA.
Contact header is ok.
Could that be the reason that im getting calls rejected?
Is there a way to rewrite the VIA header?
Im including the configuration file i have and some packet dumps of the
calls.Thanks!

Just wanted to add that I also get the warning: I
wont send a reply
for ACK.
I guess that means ACK from UA behind NAT dont reach the pstn gw?
No, this means that your config is broken and you are trying to send
replies for incoming ACK requests.

klaus
thanks,

Subject: [Serusers] Calls from UAs behind NAT getting a 503 error...
Hi,
calls from a UA that is on public ip go through the pstn gw and
terminate ok.
Calls from behind NAT get a 503 error from the GW when the INVITE
message is sent from SER.
The invite messages for both cases are the same except from the VIA
header which for the latter one contains the private ip of the UA.
Contact header is ok.
Could that be the reason that im getting calls rejected?
Is there a way to rewrite the VIA header?
Im including the configuration file i have and some packet dumps of
the calls.Thanks!

So Klaus, basically what i need is an extra handler for ACK?
route[6] {
# ------------------------------------------------------------------------
# ACK Handler
# ------------------------------------------------------------------------
if (method=="ACK") {
t_relay();
return;
};
Does this affect the call flow?
Im a newbie in SER and sip so please bare with me.
:-)
By the way thanks for the reply.

I guess that means ACK from UA behind NAT dont reach the pstn gw?
No, this means that your config is broken and you are trying to send
replies for incoming ACK requests.

Subject: [Serusers] Calls from UAs behind NAT getting a 503 error...
Hi,
calls from a UA that is on public ip go through the pstn gw and
terminate ok.
Calls from behind NAT get a 503 error from the GW when the INVITE
message is sent from SER.
The invite messages for both cases are the same except from the VIA
header which for the latter one contains the private ip of the UA.
Contact header is ok.
Could that be the reason that im getting calls rejected?
Is there a way to rewrite the VIA header?
Im including the configuration file i have and some packet dumps of the
calls.Thanks!

New subject: [Serusers] Please help in configuring SER tools
Hello Forum,
I am very new to this forum, Can any one help me in configuring serweb or
SERadmin, I am strrugling since long to configure one out of them, but it
sucks.
Or any one can provide me any other admistration tool to manage and access
the Sip Express Router.
I will be very thankful.....
Regards

Subject: Re: [Serusers] Calls from UAs behind NAT getting a 503 error...
So Klaus, basically what i need is an extra handler
for ACK?
route[6] {
# ------------------------------------------------------------------------
# ACK Handler
# ------------------------------------------------------------------------
if (method=="ACK") {
t_relay();
return;
};
Does this affect the call flow?
Im a newbie in SER and sip so please bare with me.
:-)
By the way thanks for the reply.
Kyriakos
