VONR : SIP REGISTERING : 403 Forbidden - HSS User Unknown #315
Comments
Please post a pcap file in order to know what/where the issue is. Also, are you using COTS UE or some VoIP UA? |
Thank you for your answer. Here is the PCAP file. We can see that on the SIP register request we do not have the field " Authorization, digest username, realm, uri, algorithm etc..." |
If you are using pyHSS, then provide password in |
ok i'm going to try it thank you, we have to find the username field also |
Its seems IMSI in the IMS subscriber is the username field |
It works !!! with IMSI in the username field and KI in the password field. Thanks a lot for your answer. |
I dont understand what you mean here. Can you please elaborate? |
Have a look at the pcap and you'll understand |
Hello, i have more detailled news for you. |
here i give you a pcap file which is successful from an other contributor of your blog. Comparing this one to mine we can see that my P-CSCF is not adressing the I-CSCF to register the UE by the S-CSCF. The 3 network functions are not talking to each other |
I dont see any major issue here except that UE is not sending SUBSCRIBE message with IMPU. And, you are seeing the below packet with 403 Forbidden in for the UE but for one of the previously registered SIP Contact i.e. different ports Notice that there is 200OK (packet 14) for SIP OPTIONS done in packet 13 because it matches the SIP Contact which is currently registered |
I think it's a routing or a port issue but i don't know where to fix it ? thanks for your help |
do you have some ideas ? i noticed that the PCAP successfull of our partners on your blog had the contact header filled in the first registration request of the UE |
@herlesupreeth it works perfecto for 4G! |
i can see tel: +7 in the logs while the number starts with 01987... Nor even sending SMS |
@herlesupreeth |
Thats because its not supported :) . The configuration files required to enable VoNR are not yet made public by the developer |
Hello,
I think i'm missing something with the UE authentication threw HSS. I provided all the info about the APN, AUC, SUBSCRIBER, IMS SUBSCRIBER. But i'm missing something with the sip authentication, i think i need to enter an username and maybe be password for the digest authentication but i don't know where ? Is it in the tables of the SCSCF database ? Thank for your help
Here is the wire shark log of the SIP registration request and the 403 error
