Hi,
i've tested Kamailio IMS with the following handsets on IPv4 only: - Samsung S4/S5/S6/S6 Edge - IPhone - OnePlus 3/3T/5 - Microsoft Lumia (various models)
I am currently on holiday. I think in our APN reply we do not provide any IPv6 P-CSCF, even if the client requests this.
Thanks, Carsten

I would like to support VoLTE using an IPv4 IMS network rather than IPv6 network. The handsets that I have been trying insist on the IMS network support either IPv6 or IPv4v6 dual stack. After giving them IPv4v6 connectivity, I am finding that even though the handsets asked for both IPv4 and IPv6 P-CSCFs, they only try the IPv6 proxy (if only the IPv4 proxy is provided, they will not try at all).
I am wondering of anyone has worked with any LTE handsets which are willing to support IMS using IPv4 only.
Thanks,
Ron
