Actually we require this behavior in case of SAE.

UE ----ePDG-----PGW

So here IPSEC tunnel is established between UE and EPDG.

If i remember well,
a IPSEC tunnel is not required on UE to IMS communication in LTE/VoLTE.
The mme should accept emergency attach, and then the UE connects to the e-cscf throught the p-cscf (using an emergency apn).

Hi,

With emergency call, I mean if user is not authenticated or SIM is not inserted, still a IPSEC tunnel shall be created.
Let me put reference for section 6.1.5.1.1 from 33.234 IEEE specs.

Hi There,

Do we have support of emergency call in strongswan? If yes, then what configuration needs to be done?
If no, can we make some changes in code to work it out?

Regards
Poonam
