Thanks. Unfortunately I still can.t connect using iptel web client. Anyone?

Hi,
Consider the following scenario. UA1 is trying to call UA2 both
registered with the same proxy. (UA1 -> 'ser' -> UA2)
1.
UA1 sends INVITE to the proxy with request uri set to UA2. It also sets
the Route header in the invite to that of the proxy.
This returns a 483 - too many hops to UA1
It seems that in the above mentioned scenario, the proxy loops back the
INVITE multiple times locally. This decrements the Max Forwards value
every time until it becomes zero and hence sends 483 back to UA1. It
seems to me this is not the correct behavior of the server. It should
forward the request to UA2.
Thanks in advance,
Chintan

ps: We checked it with loose routing(suceeding ';lr' present in URIs in
Route) as well as strict routing(suceeding ';lr' not present in URIs in
Route). Should the type of routing used matter ?
Hello everyone,
I am playing around with the new CVS ser 0.8.11pre28
downloaded couple days ago. I am attaching my config
script and also the output of syslog with errors. Afer
I start ser it starts forking new processes until it
crashes the box (fills up the memory).
The script is little advanced, uses jabber,pa,msilo...
Thanks for your help. You are doing great job. Can't
wait till next release.
Peter.

Hi,
has anyone ported ser to Mac OS X? It is freeBSD so it should be
easy, but as usual, things not always are easy :-)
So before i take a plunge, I thought I'd ask.
/hans
Hi,
I want SER to handle forwarding multicast requests.
To do that, I want to realise this scenario :
All the UACs which want to belong to the multicast group need to register
themselves with the same multicast URI.
When SER receive request with that multicast URI, it looks for all the
contacts for the username of that URI in usrloc (with lookup() function call)
and then forward the request to all the contacts found (with t_relay()
function call).
But I don't want SER to forward the request to the sender.
That's why I want to ensure myself that URIs which have been added to the
destination set and the one which rewrites the request URI (after the
lookup() function call) don't match with SIP URI in the Contact header field
of the processing request.
Here is the test code :
###########################
Server: Sip EXpress router (0.8.11pre29 (i386/linux))
Platform: GNU/Linux 2.4.18-14 i686
###########################

loadmodule "/usr/local/lib/ser/modules/sl.so"
loadmodule "/usr/local/lib/ser/modules/tm.so"
loadmodule "/usr/local/lib/ser/modules/usrloc.so"
loadmodule "/usr/local/lib/ser/modules/registrar.so"
# ----------------- setting module-specific parameters ---------------
# -- registrar params --
# to add contacts in the destination set
modparam("registrar", "append_branches", 1)
# -- usrloc params --
# use SQL database for persistent storage
modparam("usrloc", "db_mode", 1)
# ------------------------- request routing logic -------------------
# main routing logic
route{
if (uri==myself)
{
(...)
# registering
if (method=="REGISTER")
{
save("location");
break;
};
(...)
# to find contacts, rewrite request URI and
# add contacts to the destination set
if (!lookup("location"))
{
sl_send_reply("404","not found");
break;
};
# Here I want to compare the destination set
# and the rewrited request URI with the Contact header
# field of the processing request before forwarding
...
# forward
if (!t_relay())
{
sl_reply_error();
break;
};
(...)
}else{
(...)
}
}
################
I think it's not possible using only ser script functionalities. I think I
have to write a specific function in a specific module to do that (based on
lookup() function).
What do you think about it ? Any suggestions are welcomed.
Thanks in advance.
Matthieu Saunier
If you are using following scripts, then you problem may be caused by the
additional ^ after =~ expression. I am a new comer to both SER and RegEx, so
I do not know why this ^ is added in some of the example scripts. Remove it
and try again.

thank u very much.
my configuration.
serrouter 's IP addr : 172.30.10.230
the PSTN GW addr: 192.168.15.41 at the gateway, there is a phone num 8010
the invite uri from my sipphone to SER is "sip:8010@172.30.10.230"
I hope after the statement rewritehostport("192.168.15.41:5060"); the
invite message's uri will be changed to "sip: 8010(a)192.168.15.41"
but from the CISCO's GW, i found the uri is the same as the original. that
is :"sip:8010@172.30.10.230"
so the GW return an 400 invalid IP addr error.

#for PSTN gateway
if (uri=~"^sip:[0-9]*") {
forward (192.168.15.41,5060); # 192.168.15.41 is my CISCO SIP2PSTN
GW.
#rewritehostport("192.168.15.41","5060")
break;
}
I just add in the default ser.cfg.
when I comment these lines. the ser can be started.
if (uri==myself) {
if (method=="REGISTER") {
# Uncomment this if you want to use digest authentication
# if (!www_authorize("iptel.org", "subscriber")) {
# www_challenge("iptel.org", "0");
# break;
# };
save("location");
break;
};
#for PSTN gateway
#if (uri=~"sip:8010") {
# forward (192.168.15.41,5060);
# #rewritehostport("192.168.15.41","5060")
# break;
#}
# native SIP destinations are handled using our USRLOC DB
if (!lookup("location")) {
sl_send_reply("404", "Not Found");
break;
};
};
can anyone tell me what 's wrong with these line.

hi, all,
i want to call from pstn to the agent which registers at ser.
but when I call the sip agent from PSTN, the CISCO gateway get the 500
server errror from ser.
d05h: Received:
SIP/2.0 500 I'm terribly sorry, server error occured (1/SL)
Via: SIP/2.0/UDP 192.168.15.41:5060
From: "8010" <sip:8010@192.168.15.41>;tag=6483474-1312
To: <sip:8275@172.30.10.230;user=phone>;tag=d907c03782364451
b
Call-ID: EC4BBA87-15E311CC-82EADFF8-C6A5744F(a)192.168.15.41
CSeq: 101 INVITE
Server: Sip EXpress router (0.8.10 (i386/linux))
Content-Length: 0
Warning: 392 172.30.10.230:5060 "Noisy feedback tells: pid=2
168.15.41 in_uri=sip:8275@172.30.10.230:5060;user=phone out_
10.97 via_cnt==1"
and my sip agent can get the invite message, and the cisco gw can get my 180
after 500 error.
i have the following line in my ser.cfg
if(src_ip==192.168.15.41){
if (!lookup("location")) {
sl_send_reply("404", "Not Found");
break;
};
t_relay();
};
also I have add the usr and usr contact in the mysql db.
BTW, how can I read the debug information. In my ser.cfg, I set debug = 5;
Best Regards,
Jade
