  1. INOC-DBA Hotline Phone System Version 5.0 June 2007 Gaurab Raj Upadhaya Packet Clearing House

  2. What’s it About?  INOC-DBA: Inter-NOC Dial-by-ASN  Global Voice-over-IP hotline phone system, directly interconnecting NOCs and SIRTs within carriers, ISPs, exchange points, and vendors.

  3. How does it work?  If you just dial an Autonomous System Number, it’ll ring a predefined group of phones within that AS. (example: 42 )  If you dial an ASN and an extension number, it’ll ring the phones belonging to that person. (example: 42*WEW )  Also, well-known extensions for NOC, abuse, routing, SIRT, et cetera.

  4. How does it work?  Uses SIP.  Uses SER (SIP Express Router)  You register online  Give it a day or two to get approved  Then you configure your phone / asterisks / gateway to regsiter with the inoc-dba.pch.net  Someone dials your ASN, your phone rings

  5. Any Problems So Far?  CPE network environment: NAT and firewall traversal Unusual DHCP server options  Nothing a little static configuration can’t overcome.

  6. Unexpected Benefits  QoS is completely unnecessary.  Sound quality far exceeds that of the PSTN, even under the worst conditions.  Latency seems less annoying when it’s not accompanied by degraded sound.

  7. Is it Difficult to Set Up?  Not really.

  8. Is it Difficult to Set Up?

  9. News  Call forwarding to sip: addresses.  Conference bridge successfully tested, and available for use on request.  inoc-dba used more commonly as an interface to other voip confrence bridges.  1400+ users on the db, but lots are not 24x7 available  Asterisk seems to be a popular gateway to the inoc-dba.

  12. How to Participate  With your own phones/gateways:  Register online http://www.pch.net/inoc-dba/  With phones from us:  We need your contact and shipping address, ASNs, and extension number.  Phones from us are getting rarer
