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
- RBK
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.

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; }; }; } }

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.

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

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.

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.

Betreff: Re: [SR-Users] Kamailio IMS with ENUM
yes. when the HSS profile is not found, it did not route to DNS/ENUM to check, which portion of configuration should I check?

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.

Betreff: Re: [SR-Users] Kamailio IMS with ENUM
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.

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
