No audio with SIP calls after enabling lots of ports

I have no audio on internet phone calls on Ubuntu 19.10.

All outgoing and incoming calls, on both Linphone and Zoiper, are affected.

I have enabled ports 5060, 7078, 9078, 11078 (in both directions, for good measure, and for tcp/udp.)

After looking at the firewall log, with gufw, linphone was also asking for 7079, 9079, 11079, (?and 8610 and 8612) and a random port at around ~36000, so I enabled them and ports 32000-65535, but with no change.

It seems to be a firewall issue: when I allow all outgoing traffic on the firewall on my laptop, the problem disappears.

Why is audio blocked when I have enabled RTP ports 32000-65535?*

I note the below from the logs:

[error ] 2020-04-13 21:56:26:151 RtpSession [0x55ff9854df40] error sending [rtp] packet [0x7f19800040b0] to 217.10.77.153:19290: Operation not permitted [1

I have the linphone and ufw logs, and my .linphonerc configuration file below.

Thanks.

*Before anyone mentions it, clearly not a long-term solution for security reasons.
