[Linphone-users] SUBSCRIBE returns 407, Presence now broken

[El Pato]

Hi,

As of 1 or 2 hours ago, SUBSCRIBE is now broken for linphone PJSIP buddies.  It looks like SHA-256 is the culprit again.

2019-09-03 15:05:01.773      sip_auth_client.c  ....Unsupported digest algorithm "SHA-256"

The times in the logs are all Pacific Daylight Time.

This causes sending IM to buddies to fail.

Here is a snip from my pjsip.log.
