What Are Protocols In VoIP Telephony

VoIP protocols are the technical codings that enable voice to be carried over the internet. There are several competing standards in that field. Here you have a brief summary of these.

Perhaps the most famous VoIP protocol is the H.323 standardized by International Telecommunication Union (ITU). H.323 is very sophisticated partially due to the fact that it is not just a strict VoIP protocol but also one for interactive data sharing, videoconferencing and audio/video processing. It is actually a conglomeration of several smaller protocols, namely:

• Transport protocols H.225, H.235,H.245,H.450.1,H.450.2,H450.3,RTP,X.224.0
• Data protocols T.122,T124,T125,T126,T127
• Audio protocols G.711,G.722,G.723.1,G.728,G.729
• Video protocols H.261,H263
• Fax protocol T.38

Another smaller but very robust protocol is more geared to just VoIP. It is called Session Initiation Protocol and usually referred to as simply SIP. It consists of MIME, SDP and SIP itself.

MGCP (Media Gateway Control Protocol supported by Level 3, Bellcore, Cisco and Nortel) has also gained a substantial share of the VoIP market. Other main VoIP related protocols include Megaco H.248 (Media Gateway Control boasting great interoperability and backed by GTE, ICG, Netcom, Level 3,Sprint and founded by joint cooperation of IETF and the ITU-T Study Group 16), RVP over IP, SAPv2, SGCP and Skinny.

All these protocols are not always 100% compatible with each other therefore some possible standardization might by showing up there in the future.

And important factor in protocols application is bandwidth optimization. Signaling proxy operations are normally faster then the full proxy modes but perhaps the fastest are approaches like those of TDMoIP which deal with bundling together conversations going in the same direction.

New Nile Album Leaked!!

The new "Nile" album scheduled to
be released in May was leaked last
night from the reviewers.

It is a brilliant album and signals a
slight shift Nile's style in my opinion
anyway.
They have introduced a more catchy
chuggy style into some of the tracks
which I think is a great addition.

So far the album sounds much better
than their previous album.

Onspeed Update

I read the onspeed website carefully
and I noticed that the maximum
connection that the program works
for is a 300kbit connection.

It looks like anything over that speed
would simply be a waste of 30 quid
a year. 56k modems only. *sigh*

Job Termination

After 8 years I left my job in the bog.
I am no longer working in the garden
center and soon I will be living up in
Dublin for extended periods of time.

Its going to be great fun this summer.
I have the SNES up now so its going to
be Mario Kart every day for the summer
of course.

I left the job in the garden center due
to the political crap, bickering, bitching
and shit fest that it has turned into.
I was sick of the Boss's brothers
fighting over whether me or John was
going to work for them.

Work colleagues Part II

Lots of interesting yet annoying things have
happened at my place of work over the last 6
months or so but I have to say that plenty of
weird things happened today.

Things such as:

A young guy (16) working there who I am sure
was checking out the managers' (male) ass.
The manager also kinda caught the lad looking
at him and glared at the boy in a way as if to
say "What the fuck??" and then everything
continued as if nothing had happened. WEIRD!!

Also John (friend) and myself were chatting
during the day as we always do in work to pass
the time. Yet at various intervals the guy
beside us would butt in on our conversation
making kinda annoying comments.

He would jump in with a comment like "What
sort of a word is that? Do you even know what
it means?" John tried to explain what the word
meant but the manager came over and joked that
he was talking a load of shite. Laughter ensued
but I think John was thick.In fairness to him
he gave the correct meaning to the word
"crescendo" which means, to gradually get louder.

I said the phrase "and so I came to the conclusion"
in one of my sentences and the guy also made a
comment on that phrase too, saying that "Oh jehses,
thahs noh the way I would shay it"(intentional
incorrect spelling in quote).hehe I thought it was
kinda funny the way he was commenting on words that
I thought were pretty mainstream and acceptable.
I wonder how he would feel if he spoke to some of
the Dublin 4 (Exclusive Area of Dublin) spoilt
rich kids with accents to die for. (ie you die of
annoyance when you hear them : ) ha!).

The guy went further to comment on the word
"tolerance" also. At this point I'm afraid it
became necessary to take the piss out of the guy as
it was beginning to get annoying.
John and myself then began to discuss whether or not
"the" was a big word or not. This instantly shut him
up and nothing more was said for the remainder of the
evening concerning big words. : )

hehe Such petty little things we complain about in
work these days.*throws eyes up to sky*

Rain !

I know, I know, why the hell am I talking
about such a miserable subject?

Well today as I worked in the local Garden
Center in central Ireland (Laois), it rained
and rained all[B] day!!!!

It was misery and cold to such an extent that
I felt that it deserved a topic on my little
blog. The depression (temporary) was made worse
with the constant text messages from Sharon
(who is living in Las Palmas) about what a
wonderful day she was having at the beach.

*Shakes Raised Fist*
Damn you for rubbing it in my face.

Today, it is almost safe to say that it never
really got bright outside.
My fingers were numb as I inserted them into
the icy compost which I then used to plant
young plants into small little pots.

I am now all nice and warm in front of my PC
at home with residues of the compost still on
my fingers but I don't care.

My friend plans to go around the country side
tonight to remove the old signs from around
the country side.
He then plans to sell them on eBay to the
Americans, who love paying money for that
sort of thing. In one way it is a good idea
if it was worth a lot of money although I don't
think it is. I will check eBay tonight and
see is it a worth while risk but I don't know
what happens to people if they are caught
doing something like that.....

Also the fact that it is raining will really
limit the effectiveness of such an operation.#

Hmmmm.
