PDN Connectivity Request for VoLTE Service with PDN Type: IPv6 - IMS Not Supporting IPv6

[Sami.Sadiki]

Hello Experts.

I am having a lot of PDN connectivity request for VoLTE service with PDN type: IPV6, but our IMS does’nt support IVP6.

In this case, I am wondering if these UEs will be attached to IMS for benefiting from VoLTE service?

No, they can’t.

You should align PGW and IMS to support same IP stack.

Did you try to configure the IMS APN to IPv4 only?

I believe most phones (if not all) will accept an IPv4 IP when this is the only thing that is offered.
