Yes. UE Should establish Default Bearers with IMS PDN. While Establishing Default Bearers UE will get to know the PCSCF and DNS Adress and After that It Starts the SIP Signalling.

As per my knowledge, UE needs to establish default bearer to do IMS registration.

Is it mandatory to establish a separate default bearer to exchange IMS signaling messages between UE and IMS network nodes ? Can't internet default bearer be used for the same ?

Hi Experts,
We are facing an issue where UE sends multiple IMS-registration requests, below is the scenario
UE is successfully registered to IMS. However UE re-sends an IMS registration request with same nonce value and receives 200 OK. Why UE re-sends IMS registration while it is already registered.

Thanks in advance.
