| How to Talk to Your Media Server: SIP vs. Media Gateway Protocols |
by Garland Sharratt, Vice President of Partner Development and Chief Architect, Convedia.
This article presents the key reasons for SIP's popularity as a media server control protocol:
- Application servers use SIP for signaling, and have no need to control media gateways with MGCP or H.248, so application server vendors greatly prefer to use SIP for media servers too.
- The SIP infrastructure has powerful features that can be reused for media servers.
- The interaction between control agents and media servers is better suited to SIP than to MGCP/H.248.
- SIP is better suited for media resource brokering.
- SIP can fill the role of a converged media server control protocol, which neither MGCP nor H.248 can do.

Siemens SIP Communication System - "Push Services" are a means of getting ever-changing content to the people who need it, at the instant of change. Multimedia on-line content is nothing new, but for ages its delivery has been hamstrung by technology: bandwidth was simply not available, or prohibitively expensive, and people were seldom continuously connected. This paper takes advantage of the changes that have come with the increased availability of broadband access, and presents a solution that converges content with technology to re-establish content as something that gives more value than before. By providing good content, customers will be forthcoming.
Active Internet Services:Publish content to the People
There has to be a good reason for bringing voice out of a Telephony and into an IP world. Simply 'Doing Voice' is not a good reason: there has to be more than just a replication of what existed before. A good reason is that IP networks are inherently more flexible than Telephony networks and facilitate the combination of IP services and applications with Voice and Video. This provides a rich environment in which to do something new. This paper outlines an Advanced Application that does just that, integrating Voice, Video, the Web, E-mail, Instant Messaging, and Presence. And, in doing so, outlines the SIP architecture that is necessary behind it.
SIP Architecture with NAT
This document describes the general requirements for establishing a SIP infrastructure over the Internet. The main focus is on access technologies such as ADSL modems, ADSL Routers and Firewalls. The aim of this document is to show an architecture capable of supporting most of these access technologies.
