          • “ Testing Asterisk: Advanced Test Methodologies”
    • What we'll cover today
      • We believe Asterisk is ready for Carrier class projects
      • ... but you need well understand the Project Environment:
      • The requirements
      • The Customer's expectations
      • More important: the Customer's Commitment (you have to work with the Customer's Decision Maker people)‏
      • Your skills, in terms of
        • Technical skills
        • Project Management ability
    • A carrier grade project
      • Project overview:
      • The customers is a medium-size Telco Operator
      • The need is
        • "We have a traditional telephony infrastructure based on SS#7 protocol. We need to expand out network with a VoIP Softswitch to collect residential users."
      • Uhm... interesting... a very nice Asterisk Project (?) ... with a TON of expectations built into it
    • Project overview (1)‏
      • Our Customer:
        • TelCo for Enterprise and Residential users in the Norther of Italy
        • 10.000 customers
        • More that 50% of Top Class Enterprise in the Region covered by its Network
        • 10.000+ telephones lines
        • 7.000+ Broadbands accesses
      • The Requirements
        • A VoIP/SS#7 Platform (interconnected with Alcatel S12 voice switching system) to provide the following services for the End Users (equipped with CPE VoIP GWs):
        • VoIP calls (SIP, G.729 codec compression)‏
        • Fax
        • Voice Mail
    • Project overview (2)‏
      • Performances:
        • from 2.000 to 6.000/10.000 residential users
        • 600-1000 concurrents calls
      • Complete Fault Tolerance(24/7, 365 days/year)‏
      • SS#7 Links Management
      • Backend features:
        • Billing
        • CPE autoprovisioning
        • Complete Monitoring Dashboard for the whole system (events, alarms)‏
        • Lawfull Interception Management
      • Performances and Load Certification
    • The approach
      • Wow! A lot of technical problems to solve
      • Yes, but... there are many NON-technical issues !!!
      • First of all: this is not a standard project of integration with Asterisk. You don't have a product. You need set the correct expectations for the Customer Decision Maker People.
      • 2nd: the Marketing expectations (project not product)‏
      • Finally: Your customer NEEDS to understand the limitations of the solution. Asterisk is not a complete SoftSwitch platform (technical expectations).
    • The main goal Build the Customer Consensus (2 main steps): The Open Voice Soft Switch is not a BRANDED product: you need to build the correct “feeling” between you and your Customer. The Open Voice Soft Switch is not a READY-TO-USE product but a complete CUSTOM solution: advantages vs disadvantages.
    • The “real” big matter
      • Understand the different needs of the 2 Company divisions involved into the project:
      • Network/VoIP Division
      • PSTN Telephony Division
      • and design a platform useful for both ;)‏
    • The Open Voice Soft Switch
    • Open source technologies
      • GnuLinux Debian Etch 4.0
      • Open Voice Media Gateway: Asterisk, of course, Digium G.729 software codecs
      • Open Voice SIP Proxy: OpenSER, DRBD (for HA cluster)‏
      • Open Voice RDBMS Cluster (database and other services):
        • Web&Application server: Apache + Jetty (Java technology for the GUI Dev)‏
        • Database: MySQL
        • Monitoring Tools: Monit + Munin + custom applications.
      • Perfomances Certification:
        • Abacus 50 / Abacus 5000 (Spirent Communications)‏
    • Project phases
    • In deep lookup
      • We solved some technical “hot” problems:
      • SS#7 Links Management
      • FarEnd Alarm
      • Lawfull Interception
