[srsran-users] Unable to Establish Calling and Messaging Between Two User Equipment's ( UE's) whne using SRSRAN

[Murthy S]

Dear All,

I am running srsRAN 22.04 on my lenovo laptop having the specifications as
Intel Core i7 (8th Gen), 16 GB DDR4 RAM. I'm using ASUS ROG Phone 2 and
Oneplus 7 as my 4G UE and for both these UE's i am using Open Cells USIM
card.

I am able to run srsepc and srsenb  and connect my both UE to the network
and I am able to surf the internet with the established srsRAN network.

When I try to initiate a call from one UE (ASUS ROG Phone 2) to another UE
(Oneplus 7), I get the following message.
*Unhandled NAS integrity protected message
LIBLTE_MME_MSG_TYPE_EXTENDED_SERVICE_REQUEST*

Please help me establish a calling and messaging feature between two UE
when using srsRAN.

The message screenshot is attached, please check and let me know.
