Could you make ngrep dumps on the server ? If SER replies with 408 that
means it received the request and tried to forward it somewhere, but the
dumps below do not show anything.
Do you have any record for sip:12345@sip.interlab.ait.ac.th
in location table ?

Hi,
I am having the same problem again.... SER just keeps on sending me
back timeouts for SUBSCRIBES... The problem, as I described in
previous emails, persists for any other presentity except myself.
Here's a part of ser.cfg:
. . . . . .
if(method=="SUBSCRIBE") {
if (!www_authorize("sip.interlab.ait.ac.th", "subscriber")) {
log(1, "Authentication for SUBSCRIBE");
www_challenge("sip.interlab.ait.ac.th", "0");

log(1, "No registered user found for SUBSCRIBE request");
sl_send_reply("404", "Not Found");
break;

And so it goes, until SER replies with Timeout.
Can you tell me what is wrong???

Hi,
I think the problem is solved... I forgot to mention that if I
subscribed to myself, then it always worked... So, i plugged in the
code for authentication, and it seemed to start working well for every
other subscription. I also forgot that RFC metion, that it's a must to
authenticate subscriptions. Is that what SER must do for
subscriptions??? Is that the case?
Anyway, my SUBSCRIBE request is as follows:
SUBSCRIBE sip:12345@203.159.32.35:5060 SIP/2.0

After that the 408 Timeout was issued by SER...

Hi,
Im using ser 0.9.3. The PA and Watcher are located on my UA, so
basically my SUBSCRIBEs and NOTIFYs just need to be forwarded between
clients.
Here's a part of ser.cfg that does the SUBSCRIBE and NOTIFY
processing (please, note that I disabled the authentication for now):
. . . . . .
if(method=="SUBSCRIBE") {
if(!lookup("location") ) {
log(1, "No registered user found for SUBSCRIBE request");
sl_send_reply("404", "Not Found");
break;
};
};
if(method=="NOTIFY") {
if (!lookup("location")) {
log(1, "No registered user found for NOTIFY request");
sl_send_reply("404", "Not Found");
break;
};
};
if( !t_relay() ) {
sl_reply_error();
};
. . . . . . . .
The problem is that only SOMETIMES SUIBSCRIBEs and NOTIFYs get
through without any problem. However, MOST OF THE TIMES they get stuck
in the server. The message log does not show any errors and
tracesviewer tool shows only retransmissions for the issued requests.
In the end SER replies with 408 Timeout response. I have tried to use
forward(uri:host, uri:port) instead of t_relay(), but result is the
same.
I have used eyeBeam to do the presence subscriptions, and the result
is the same as with my UA...
Can you, please, explain to me what might have happened??? I am out of ideas.
Andrey.
