Whats 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,
itll ring a predefined group of phones within
that AS. (example 42 )
If you dial an ASN and an extension number, itll
ring the phones belonging to that person.
(example 42WEW )
Also, well-known extensions for NOC, abuse,
routing, SIRT, et cetera.

4
How does it work?

SIP is similar to Dynamic DNS.
Pick up an address via DHCP or statically
Download config from preconfigured server
Register current IP address with a SIP Registry
Registry transfers IP address to SIP Proxies
When someone calls your phone, they do a
dialed-number-to-IP-address lookup against the
proxy
Then their phone contacts yours directly.

5
Any Problems So Far?

CPE network environment
NAT and firewall traversal
Unusual DHCP server options
Nothing a little static configuration cant
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 its not
accompanied by degraded sound.

7
Is it Difficult to Set Up?

Not really.
