CCNQ4 =

  • Docker.io instead of Debian packages

    • docker package per app e.g. freeswitch, opensips, etc.
    • docker package per node.js app (but need to keep config alongside e.g. FreeSwitch, so will need _changes-based + RabbitMQ there still) -- yes, but as clients, not servers

  • node.js clustering for better throughput (esp. ESL clustering)

  • programmable LCR w/ ESL (remove outbound-proxies) → tough-rate

  • keep (LCR) vs (Billing info) separate -- NO, inject charging info into CDRs

  • fully-tested & benchmarked ESL, copes with crashes, load, etc.

  • CDRs with proper IDs & dynamic (e.g. per month, per day, per account + day, etc.) DB-names

  • routing data out of provisioning db; one routing DB per routing profile; summarize rules (digit patterns) into routes (e.g. "SP.mobile") for provisioning purposes (bulk edits, basically)

  • conntrack etc. for mediaproxy failover

  • more _changes monitors

  • freeswitch reload_acl etc

  • RabbitMQ automation (using rabbitmq-management plugin and its API)

  • proper RabbitMQ <-> browser integration (e.g. Socket.IO, sock.js, etc.)

  • recent (>=1.4) FreeSwitch

  • logs!! (winston, winston-irc, winston-amqp, winston-nodemailer)

  • metrics!!

  • IPv6

  • use CouchDB _replicator instead of our own (i.e. make it a provisioning operation, not a local, runtime operation)

  • since we're using Docker, all accesses must be (a) authenticated and (b) encrypted. Use Node.js' tls.connect() and tls.CreateServer()'s ca option to that goal (and provide / copy a toolbox for CA management) -- ideally automate that as well during Docker image creation.

  • provide proper certificates to CouchDB, RabbitMQ, OpenSIPS, and FreeSwitch

  • use JSON interface for OpenSIPS (the one I wrote!)

  • SIP & media redundancy

    • OpenSIPS replication / state propagation
    • MediaProxy + conntrackd
    • FreeSwitch redundancy

  • legal intercept (e.g. conntrack stream replication)

  • I-PBX interco (with e.g. FS frontending)

  • multi-site (e.g. centralized SBC + local OpenSIPS)

  • CouchDB redundancy

    • BigCouch
    • ManyServers (ReallyHorizontal)

  • Vertical Services

    • web
    • tel

  • Billing & Cost in CouchDB

    • insert billing & costing data in routes
    • add "destinations" to automate updating
    • billing & costing injected into CDRs for realtime
    • one CDR database per billing cycle
    • issues: French Added-Value Services (SVA), French short numbers, full vs low-cost hours (e.g. 3303994)

  • new routing architecture:

    • inbound: replace ENUM with ESL code; routing is done inside FreeSwitch (via context redirection)
    • inbound: put carrier-side and client-side inside same FreeSwitch process
    • inbound: FreeSwitch-only server (on ex-carrier-side-SBCs) & OpenSIPS-only server (on ex-client-side-SBCs)
    • outbound: replace OpenSIPS LCR with ESL code
    • outbound: FreeSwitch-only server in two parts, one part up to and including LCR and carrier-side translation, second part with call-state only (all identical) or registrant
