[SR-Users] Presence between different domains

[Manuel Perez]

Thanks for your reply.

This is part of my config file:

request_route {
# per request initial checks
route(REQINIT);

# NAT detection
route(NATDETECT);

# handle requests within SIP dialogs
route(WITHINDLG);

### only initial requests (no To tag)

# CANCEL processing
if (is_method("CANCEL"))
{
if (t_check_trans())
t_relay();
exit;
}

t_check_trans();

# authentication
route(AUTH);

# record routing for dialog forming requests (in case they are routed)
# - remove preloaded route headers
remove_hf("Route");
if (is_method("INVITE|SUBSCRIBE|NOTIFY"))
record_route();

# account only INVITEs
if (is_method("INVITE"))
{
setflag(FLT_ACC); # do accounting
}

# dispatch requests to foreign domains
route(SIPOUT);

### requests for my local domains

# handle presence related requests
route(PRESENCE);

# handle registrations
route(REGISTRAR);

if ($rU==$null)
{
# request with no Username in RURI
sl_send_reply("484","Address Incomplete");
exit;
}

# dispatch destinations to PSTN
route(PSTN);

# user location service
route(LOCATION);

route(RELAY);
}

route[RELAY] {

# enable additional event routes for forwarded requests
# - serial forking, RTP relaying handling, a.s.o.
if (is_method("INVITE|SUBSCRIBE|NOTIFY")) {
t_on_branch("MANAGE_BRANCH");
t_on_reply("MANAGE_REPLY");
}
if (is_method("INVITE")) {
t_on_failure("MANAGE_FAILURE");
}

if (!t_relay()) {
sl_reply_error();
}
exit;
}

route[WITHINDLG] {
if (has_totag()) {
# sequential request withing a dialog should
# take the path determined by record-routing
if (loose_route()) {
if (is_method("BYE")) {
setflag(FLT_ACC); # do accounting ...
setflag(FLT_ACCFAILED); # ... even if the transaction fails
}
if ( is_method("ACK") ) {
# ACK is forwarded statelessy
route(NATMANAGE);
}
route(RELAY);
} else {
if ((is_method("SUBSCRIBE| NOTIFY")) && uri == myself) {
 route(PRESENCE);
exit;
}
if ( is_method("ACK") ) {
if ( t_check_trans() ) {
# no loose-route, but stateful ACK;
# must be an ACK after a 487
# or e.g. 404 from upstream server
t_relay();
exit;
} else {
# ACK without matching transaction ... ignore and discard
exit;
}
}
sl_send_reply("404","Not here");
}
exit;
}
}

I'm using loose_route function in WITHINDLG function, presence in the same
server works buts with user from another domain I receive duplicate
notifys. The request line for this notifys is userB at ip_of_domainB not
userB at ip_of_userB like the ones I receive when the two users are in the
same domain.


Thanks.
Regards.
