| SIP-URI User: | UserName |
| SIP-URI Host: | Domain |
| SIP-over-TLS: | Advanced → Transport: TLS … TLS Cert Management: Verify TLS Cert since 9.2: TLS does not work for me at all: ‘no transport left to try’ |
| SDES-sRTP: | Sign In → Settings → Preferences → SRTP: Prefer which is RTP/SAVP |
| SHA-2 Digest: | does not pick MD5, continues without header Authorization, therefore is not able to register; therefore incompatible with Linphone |
| AES-256 sRTP: | accepted although not supported; therefore no audio |
| Bugs: | SIP-over-TLS without authentication because ‘Verify TLS Cert’ failed for me |
