<strong>SIP</strong> Overview<br />
5
<strong>SIP</strong> Definition<br />
<strong>SIP</strong> is a request-response protocol<br />
• Handles requests from clients and responses from servers.<br />
• Participants are identified by <strong>SIP</strong> URLs known as AOR – Address<br />
of Record.<br />
• Requests can be sent through any transport protocol, such as<br />
UDP or TCP.<br />
• <strong>SIP</strong> determines the end system to be used for the session, the<br />
communication media and media parameters, and the called<br />
party's desire to engage in the communication.<br />
• Once these are assured, <strong>SIP</strong> establishes call parameters at either<br />
end of the communication, and handles call transfer and<br />
termination.<br />

<strong>The</strong> <strong>SIP</strong> <strong>Trunking</strong> Advantage<br />
• Lower Pricing<br />
– Combine 3 communication requirements;<br />
voice, video, and data into 1 supplier pipe<br />
• Scalability<br />
– On-demand addition of <strong>SIP</strong> trunks<br />
• Geological abstraction of DIDs<br />
– You can have a local appearance but not a<br />
local presence.<br />
• Disaster recovery<br />
– Quicker to deploy than traditional TDM<br />

<strong>Provider</strong> Offers<br />
• Tell me about your <strong>SIP</strong> <strong>Trunking</strong> offers!<br />
– Contacted 11 different providers<br />
• 3 had no contact information other than an online form –<br />
all 3 were filled out completely but no return calls or e-<br />
mails<br />
• 1 had no actual <strong>SIP</strong> offer although their website listed <strong>SIP</strong><br />
<strong>Trunking</strong> as an offer<br />
• 5 provided pricing with no qualification!<br />
• 2 responses were vague, directing inquiries to a forwarded<br />
.pdf (read this and get back to us)<br />
• 5 offers promoted hosted <strong>SIP</strong> services<br />
• 4 offers relied on ISP connectivity<br />
17
<strong>Provider</strong> Pricing Examples<br />
• <strong>The</strong> “Hosted Offers”<br />
– <strong>The</strong> 5 providers that offered hosted offers each were utilizing<br />
Asterisk ®<br />
• “Asterisk ® is a complete PBX in software. It runs on Linux, BSD and MacOSX<br />
and provides all of the features you would expect from a PBX and more.<br />
Asterisk ® does voice over IP in many protocols, and can interoperate with<br />
almost all standards-based telephony equipment using relatively inexpensive<br />
hardware.”<br />
18<br />
• “<strong>The</strong> Asterisk ® Development team has released another beta test release of<br />
Asterisk 1.4, 1.4.0-beta3.<br />
This release also contains a number of bug fixes, and some improvements to<br />
the chan_sip channel driver (for <strong>SIP</strong> devices) to mitigate the impacts of a<br />
certain class of denial-of-service attacks that have recently been published.<br />
Note that Asterisk ® 1.4 is not vulnerable to the chan_skinny exploit that<br />
resulted in updated releases of Asterisk ® 1.0 and Asterisk 1.2.<br />
<strong>The</strong> team has also released Zaptel 1.4.0-beta2 and Asterisk ® -Addons 1.4.0-<br />
beta2; these releases contain only bug fixes and minor improvements.”
<strong>Provider</strong> Pricing Examples<br />
• Some of the offers were humorous<br />
– Get rid of that outdated PBX!<br />
– Our solution works with your existing PBX!<br />
– 100% Internet Connectivity!<br />
• Eliminate all costly analog lines and PRIs!<br />
– Hang on to a few 1FB’s for 911 and faxing<br />
• QoS<br />
– <strong>The</strong> ISP/Hosted connectivity offers presented MTR and<br />
availability SLA’s, but no QoS<br />
• Off-Net/On-Net offers<br />
– Most providers offered both off-net and on-net<br />
– Some were off-net only and had structured pricing for interstate<br />
and intra-state calls<br />

Avaya SES<br />
COMPACT<br />
Avaya <strong>SIP</strong> Enablement Services (SES), part of the Converged<br />
Communications Server family, create a communication services layer<br />
within the Avaya Communications Architecture that mediates between<br />
Avaya MultiVantage applications and a wide range of standards-based<br />
user agents, web-based applications, and communication devices. <strong>The</strong>se<br />
services combine the standard functions of a <strong>SIP</strong> proxy/registrar server<br />
with <strong>SIP</strong> trunking support and duplicated server features to create a highly<br />
scalable, highly reliable <strong>SIP</strong> communications network. This resulting<br />
network supports telephony, instant messaging, conferencing, and<br />
collaboration solutions.
