SIP Capabilities
- Base specs:
- Core methods: RFC 3261: INVITE, CANCEL, BYE, REGISTER, OPTIONS, INFO
- Digest authentication (RFC 2617)
- Transports:
- UDP, TCP, TLS (server or mutual)
- DNS SRV resolution (RFC 3263)
- IPv6 (UDP only)
- QoS (DSCP, WMM)
- Routing/NAT:
- Call:
- SDP:
- Multipart (RFC 2046, RFC 5621)
- Presence and IM:
- Other extensions:
- Compliance, best current practices:
- Issues with Non-INVITE transaction (RFC 4320)
- Issues with INVITE transaction (RFC 4321)
- Multiple dialog usages (RFC 5057)
- SIP torture messages (RFC 4475, tested when applicable)
- SIP torture for IPv6 (RFC 5118)
- Message Body Handling (RFC 5621. Partial compliance: multipart is supported, but Content-Disposition header is not handled)
- The use of SIPS (RFC 5630. Partial compliance: SIPS is supported, but still make use of transport=tls parameter)
NAT Traversal
- STUN:
- RFC 5389
- Some RFC 3489 compatibility
