SIP over LTE no audio after upgrade

I upgraded to 1.13 on my OnePlus Nord a couple of days ago. So far everything seems ok except that there is no longer any audio on SIP calls over LTE. SIP over wifi is fine. Anyone have any ideas?

Ok, probably a SIP client problem. It works with ICE enabled on LTE but not wifi and vice-versa.

Damn Linphone! I want to love it but it breaks so frequently. Moved reluctantly to Sipnetic and problem solved.


Sorry Linphone, it’s not your fault.
It turns out that everything works without ICE on the UK Vodafone network but not on the EE network.
A new SIM has been ordered.
