Description:
Encryption for SIP payloads using SRTP. Libsrtp seems like an obvious starting point, but any implementation can be used.
the bounty will be split in several parts:
1) $100 for an asterisk -> asterisk SRTP implementation. The code does not have to cover all SRTP features: simply securing SIP payloads between two hosts with the same administrator is sufficient. On the other hand, the code must be written with future inter-operability and non asterisk peers in mind. Minimal re-writes should be required for adding proprietary key distribution, SRTCP, &etc.
2) $120 for an SRTP implementation that interoperates with an ATA that can be bought for less than $100 US. Sipura preferred. This should allow the ATA to initiate or receive encrypted payload from the asterisk server.
3) $150: Encrypted SIP signalling channel (TLS) between two asterisk machines . As above, code MUST be designed for future interoperability. needs to encrypt signallng for a full SIP session between hosts with the same administrator/shared trust.
4) Encrypted SIP signalling channel between Asterisk and cheap ATAs. $30
5) ISDN Encrypted calls with ZRTP/S protocol (ZRTP for non-voip telephony technologies) . $1500
Code should be disclaimed for inclusion to CVS.
Completion is defined as having set of documentation & patches that one can use to successfully install the software & create a call between two servers.
