asterisk and linphone config

[jay928374293]

I have connected Linphone iOS app to my Asterisk server.
Outgoing calls are fine
Incoming calls result in a 488 not acceptable here from Linphone.

What is the correct configuration required on Asterisk 20 (pjsip) to receive calls on Linphone 5.2.0 ?
I have tried enabling/disabling ice, avpf, srtp in both ends without luck.
For other phone types we have ice disabled, and avpf, srtp, tls enabled.

Linphone log for declined incoing call:
