Hi
Is there any information that can help to setup ENUM query in Kamailio
IMS? what we wanted to achieve is to when A in domain A (the local
domain) makes an INVITE to B, it will check the domain of B from ENUM
backend.
if it is not on the local domain, it will route to remote IMS core.
Thanks

The example I-CSCF and S-CSCF configurations at misc/examples/ims contain usage of the
enum module, afaik.
This could be easily adapted or taken as an example.

Thanks. I actually keep having "604","Does not exist anywhere - HSS
User Unknown", so by right, I-CSCF should go to check the ENUM, but it
didn't so what configuration I should enable? is it dispatcher list
and needed to enabkle PEERING? below is the routine that related to
"604","Does not exist anywhere - HSS User Unknown" in icscf.

This means the HSS had answered the user is not known in this domain
(lir_term_user_unknown), but then the DNS server insists this telephone number should be
handled by our domain ($rd == NETWORKNAME).
Just enter the user to the HSS database - if it shall be handled by this domain -
Or configure DNS, so that this telephone number is routed to another domain. - if it shall
be handled by a different domain.

I don't know your DNS server nor your addressing plan. Probably to modify / add some
zone files
You must be sure to forward the ranges of telephone numbers that you want to forward to
the other domain.
Actually, it DID the request to the DNS/ENUM, but the result was "keep the domain as
it is" or "replace it by the own domain"
If the DNS/ENUM query did NOT succeed, then you would run into route(PSTN) and the request
would be forwarded to "good old CS domain" to find a destination.

Hello
I may not describe the problem clearly. When a UE call a number to the
Kamailio IMS core, says, the number is 12345678, the R-URI in the SIP
INVITE is
"sip:12345678;phone-context=ims.mnc001.mcc001.3gppnetwork.org@ims.mnc001.mcc001.3gppnetwork.org;user=phone",
Kamailio P-CSCF pass to INVITE to S-CSCF, and then S-CSCF pass to
I-CSCF, I-SCSF trigger LIR to HSS with Public-Identity = tel:12345678,
This IMPU did not provision in HSS, so HSS response with
"DIAMATER_ERROR_USER_UNKNOWN".
On receiving this LIA, I-CSCF return to S-CSCF with "604 Does not
exist anywhere - HSS User Unknown", and then forward to P-CSCF and the
UE.
My question is why I-CSCF did not trigger a DNS/ENUM query after receiving LIA?
attached is the Kamailio configuration that we are using, please advise.

The example I-CSCF and S-CSCF configurations at misc/examples/ims contain usage of the
enum module, afaik.
This could be easily adapted or taken as an example.

Betreff: [SR-Users] Kamailio IMS with ENUM
Hi
Is there any information that can help to setup ENUM query in
Kamailio IMS? what we wanted to achieve is to when A in domain A
(the local
domain) makes an INVITE to B, it will check the domain of B from ENUM backend.
if it is not on the local domain, it will route to remote IMS core.
Thanks

Hi,
There are two funny things, which I do not understand:
1. The first (orig) S-CSCF should already replace the TEL URI by a SIP URI and do an
ENUM query:
Lines 1140 – 1158 of Kamailio_scscf.cfg:
route[PSTN_handling]
{
# First, we translate "tel:"-URI's to SIP-URI's:
# $ru: tel:+(34)-999-888-777
# $fu: sip:test@foo.com
# becomes $ru: sip:+34999888777@foo.com;user=phone
if (tel2sip("$ru", "$fd", "$ru") < 0)
<------THIS SHOULD CONVERT TEL URI to SIP URI a)
xlog("L_WARN","Failed to convert $ru to a sip:-URI - M=$rm
R=$ru F=$fu T=$tu IP=$si:$sp ID=$ci\n\n");
if ($rU =~ "\+[0-9]+") {
# Now let's check, if the number can be found in ENUM:
if(!enum_query()) {
# ENUM failed, send it to the PSTN-Gateway:
route(PSTN);
break;
}
}
}
1. Do you have .pcap’s from the traffic between first S-CSCF and I-CSCF? What is the
Request URI?
You can take detailed logs (#define WITH_DEBUG in scscf.cfg) and analyse them -> if
necessary, we can help with analysis
1. 2. If the I-CSCF actually receives a TEL URI (what we do not know yet), then “why
the heck do not we call the enum_query()”? Why do we hit the “604 Does not exist
anywhere”?
b) Let’s keep these questions, until we know, if the S-CSCF has actually sent a TEL URI to
the I-CSCF in the Request Line of the INVITE.
Lines 537 – 576 of kamailio_icscf.cfg:
route[lir_term_user_unknown]
{
if (uri =~ "tel:.*") {
# Let's check, if the number can be found in ENUM:
if(!enum_query()) {
# ENUM failed, send it to the PSTN-Gateway:
route(PSTN);
break;
}
# ENUM resolved to another domain
if ($rd != NETWORKNAME) {
t_on_reply("initial_request_reply");
t_on_failure("initial_request_failure");
if (!t_relay()) {
t_reply("500","Error forwarding to external
domain");
exit;
};
exit;
} else {
t_reply("604","Does not exist anywhere - HSS User
Unknown");
exit;
};
} else {
# we received a request for our domain (non-tel), but HSS said "User
Unknown"
if ($rd != NETWORKNAME) {
t_reply("604","Does not exist anywhere - HSS User
Unknown");
exit;
} else {
# try to forward non-tel request to other domain
t_on_reply("initial_request_reply");
t_on_failure("initial_request_failure");
if (!t_relay()) {
t_reply("500","Error forwarding to external
domain");
exit;
};
exit;
};
};
}
Hope it helps
Christoph

Betreff: Re: [SR-Users] Kamailio IMS with ENUM
Hello
I may not describe the problem clearly. When a UE call a number to the Kamailio IMS core,
says, the number is 12345678, the R-URI in the SIP INVITE is
"sip:12345678;phone-context=ims.mnc001.mcc001.3gppnetwork.org@ims.mnc001.mcc001.3gppnetwork.org;user=phone",
Kamailio P-CSCF pass to INVITE to S-CSCF, and then S-CSCF pass to I-CSCF, I-SCSF trigger
LIR to HSS with Public-Identity = tel:12345678, This IMPU did not provision in HSS, so HSS
response with "DIAMATER_ERROR_USER_UNKNOWN".
On receiving this LIA, I-CSCF return to S-CSCF with "604 Does not exist anywhere -
HSS User Unknown", and then forward to P-CSCF and the UE.
My question is why I-CSCF did not trigger a DNS/ENUM query after receiving LIA?
attached is the Kamailio configuration that we are using, please advise.

I don't know your DNS server nor your addressing
plan. Probably to
modify / add some zone files
You must be sure to forward the ranges of telephone
numbers that you want to forward to the other domain.
Actually, it DID the request to the DNS/ENUM, but the
result was "keep the domain as it is" or "replace it by the own
domain"
If the DNS/ENUM query did NOT succeed, then you would
run into route(PSTN) and the request would be forwarded to "good old CS domain"
to find a destination.

yes. when the HSS profile is not found, it did not
route to DNS/ENUM to check, which portion of configuration should I check?

"604","Does not exist anywhere - HSS User Unknown", so by right,
I-CSCF should go to check the ENUM, but it didn't so what configuration I should
enable? is it dispatcher list and needed to enabkle PEERING? below is the routine that
related to "604","Does not exist anywhere - HSS User Unknown" in
icscf.
