# Erlang SIP and SDP library
## Documentation
Full module documentation is available [here](https://github.com/poroh/ersip/blob/master/doc/README.md).
## Approach to design
What you cannot find in ersip:
+ Supervisors
+ Servers
+ ETS
+ Dependencies
You can find only pure functions that are compliant to SIP specification.
## Real world examples
Working examples:
+ Stateful SIP proxy: https://github.com/poroh/ersip_proxy
+ Hunt group service (B2BUA) example: https://github.com/poroh/piraha
## Provided primitives
Primitives that provided by SIP stack:
+ Connection parser split streams and retrieve low level SIP messages (ersip_conn)
+ Low level SIP message processing (ersip_msg)
+ Lazy high-level SIP message processing (ersip_sipmsg)
+ Transactions support (ersip_trans)
+ Basic UAS support (ersip_uas)
+ Registrar function support (ersip_registrar)
+ SIP stateful proxy function support (ersip_proxy)
+ SIP common dialog support (ersip_dialog)
## Supported RFC
RFC supported in this SIP stack:
+ RFC 2543 SIP: Session Initiation Protocol (backward compatibility)
+ RFC 3261 SIP: Session Initiation Protocol (partially):
- 7 SIP Messages
- 8.2 UAS Behavior
- 9 Canceling a Request
- 10 Registration - Registrar part only
- 12 Dialogs
- 16 Proxy Behavior
- 17 Transactions
- 18 Transport
- 19 Common Message Components
+ RFC 3262 Reliability of Provisional Responses in the Session Initiation Protocol (SIP)
- 6 Definition of the PRACK Method
- 7 Header Field Definitions
- 7.1 RSeq
- 7.2 RAck
+ RFC 6026 Correct Transaction Handling for 2xx Responses to Session Initiation Protocol (SIP) INVITE Requests
+ RFC 3581 An Extension to the Session Initiation Protocol (SIP) for Symmetric Response Routing (rport)
+ RFC 4475 Session Initiation Protocol (SIP) Torture Test Messages
+ RFC 5118 Session Initiation Protocol (SIP) Torture Test Messages for Internet Protocol Version 6 (IPv6)
+ RFC 4566 SDP: Session Description Protocol (partially)
+ RFC 3515 The Session Initiation Protocol (SIP) Refer Method (header/method only):
- 2.1 The Refer-To Header Field
+ RFC 6665 SIP-Specific Event Notification (header/method only)
- 8.2.1. "Event" Header Field
- 8.2.3. "Subscription-State" Header Field
+ RFC 3891 The Session Initiation Protocol (SIP) "Replaces" Header (header only)
- 6.1. The Replaces Header
+ RFC 3966 The tel URI for Telephone Numbers
