[srslte-users] IMS integration

[Tri-Khiem William Truong]

Dear srslte,

I was wondering if it was possible to use IMS with srsLTE.

Currently I have found the kamailio IMS in a box from Franz Edler to  
be the one I can run successfully.

I'm using an iphone 6s as the UE and a B210 as ENB. The connection is  
successful and I have access to the internet from the UE.

 From wireshark, I can see the phone asking for an apn called "ims".

In the console output, I see "Unhandled NAS integrity protected  
message LIBLTE_MME_MSG_TYPE_PDN_CONNECTIVITY_REQUEST".

So I was thinking if there would be a way to take the request from the  
phone and direct it to Kamailio.

I have attached some logs and capture files.

If anyone has experience in that and don't mind sharing it would be  
greatly appreciated.

Thank you,

William
