VoIP , or VoIP (Voice over IP) is a technique for communicating orally over IP-enabled networks , whether private networks or the Internet. , wired (cable / ADSL / optical) or not (satellite, wifi, GSM) . This technology is most often used to support.

How is the voice transported?

The transport of voice over IP is relatively complicated. The first step is the digitization (coding) of the acoustic signal. Then, the information is divided into frames (blocks of information) that can circulate on a computer network. Many protocols can then be used to route the information to the recipient (s).

How is the voice coded?

In a conversation, the voice produces sounds at different frequencies .

Thanks to these constant frequency changes, we perceive emotions and intonations. This multitude of frequencies would be remarkable by a sinusoidal display if one visualized his signal on an oscilloscope.

The voice causes a sinusoidal signal, which is analog . However, to pass it over a TCP / IP (Digital) network, it will be necessary to convert this signal (analog to digital) in PCM (Pulse Code Modulation) format to 64 kb / s.

Once converted, it is necessary to compress the voice (digitized) through a codec (Compressor / Decompressor) to insert it into an IP packet. This coding must offer the best possible voice quality for the lowest bit rate and compression delay possible. There are several coding techniques that are measured in a completely subjective way.

The method of broadcasting Voice over IP:

The term "VoIP" is generally used to describe " point-to-point " communications . For the broadcast of sound or videos over IP in multipoint mode , it is more about streaming for a simple broadcast, as used by web radio for example. The term multipoint is rather reserved for videoconferences.

Globex Teleccom technique can be done in unicast mode (a transmitter and a receiver), broadcast (a transmitter and all receivers without exception) or multicast (a transmitter and several receivers) on networks .

Voice over IP leads to the replacement of traditional telephones with "IP telephones" whose characteristics are:

  • Replacement of telephone jacks (RJ11) with network jacks (RJ45).
  • Replacement of analog or digital interfaces of telephones with the network through an IP protocol interface .
  • The replacement of the traditional telephone signaling protocol by an IP voice system.
  • The replacement of the handset by a new handset having the above characteristics, or by software that can be installed on a computer (with a headset and a microphone).

Accessibility:

An IP voice infrastructure may be available for the same availability zones as traditional telephone systems:

  • In a closed way ( Intranet ): by the use of a private IP central office .
  • In a semi-public way ( Extranet ): by sharing an IP central office with its partners or customers (via a VPN for example = extension of the local network).
  • In a public way but limited (Internet): by an opening on the Internet of the central IP.
  • In a public and open way (Internet): by an opening on the Internet of the central IP and the affiliation of gateway (s) towards the PSTN network .

You Are NOT Enough

We will never be enough, but God is always more than enough.

Society and even the church seem to constantly encourage us with the saying "You are enough," and their intentions behind this statement are totally innocent. Something about this phrase has always bothered me, though, but I never understood why. In a sermon I heard one Wednesday night a week or so ago, the verses Proverbs 30:7-9 were used, and these verses stood out to me in a big way.

Proverbs 30:7-9

7 "Two things I ask of you, Lord;
do not refuse me before I die:
8 Keep falsehood and lies far from me;
give me neither poverty nor riches,
but give me only my daily bread.
9 Otherwise, I may have too much and disown you
and say, 'Who is the Lord?'
Or I may become poor and steal,
and so dishonor the name of my God.

The speaker was specifically focusing on verses 7-8, but the Holy Spirit kept drawing me to verse 9, even days and weeks after. So I decided to dig into it. This verse focuses on Agur (the speaker in the passage) and his tendency to sin. When he asked God to provide "only [his] daily bread," and then when he continued on to speak about the specific sins he was afraid of committing, Agur was completely and wholly surrendering his struggles with temptation and sin to God, because Agur knew he couldn't do it on his own.

Aren't we all like Agur? Because we are human, we mess up all the time and fall into sin more than we would like to admit, and many times because of this, we fall into guilt and shame. This is because, on our own, we aren't enough. If we were enough on our own, we wouldn't sin. If we were enough on our own, we would be able to save ourselves. If we were enough on our own, we wouldn't need God. But none of those statements are true, are they? In fact, it is the exact opposite because God is enough, he calls us out of sin. Because God is enough, He sent Jesus to save us from our sin. Because God is enough, He is with us in every situation because we call to Him.

How do we know that we aren't enough? Because no one is!

Every human sins, even great heroes of faith. David, one of the most well-known biblical figures: the one who killed Goliath and one of the ancestors of Jesus Christ, said in Psalm 51:5--

Surely I was sinful at birth,
sinful from the time my mother conceived me.

The beauty in realizing that you aren't enough on your own is that you don't have to be! Never in the Bible does God call us to be "enough!" He never expected us to be enough because it is impossible. God does call us to depend on Him, though. This is because God is ultimately more than enough. When we depend on God to help us keep away from sin and put in the work necessary to keep away from sin, it will be much easier. We will never be enough, but if we continuously search for our identity in worldly things and not Christ, we will be upset when we realize that we are not enough. Guess what, though, when we find our identity in what Christ says about us, we will find peace and hope because just like 2 Corinthians 12:9 says:

9 But he said to me, "My grace is sufficient for you, for my power is made perfect in weakness." Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest on me.

God is the only one who is enough. When we depend on God for everything we will begin to see that HE is enough, and that's all we need.

Exclusive Interview With Soul Singer December Rose

Exclusive Interview With Soul Singer December Rose

Soul Singer Rosie La Posta who goes under the moniker of December Rose releases the ballad Hanging On. Finding a vocal style of her own, she hits all the notes effortlessly. You can hear past influences but she still keeps contemporary. Think Andra Day'smega smash Rise Up. As far the inspiration behind the song, Rosie says, "Besides the grief of a crumbling relationship, the hardest part in moving on is realizing neither person ever really closed the door. 'Hanging On' really paints the melancholy of the process." She first made waves her first single "Ball Game" which received a New Artist Spotlight award and was featured on AOL/Slacker Radio's "New Pop First" channel. Give it a stream.

Can you tell us a bit about your new song Hanging On?

For sure! So 'Hanging On' is about the "elephant in the room" everyone is ignoring. The relationship is crumbling, no one's letting go and closing the door to that chapter in their lives. The song carries listeners through the reminiscing sweet encounter and desperate plea for truth to set them free.

How would you describe your sound?

Always the hardest question to answer!! haha With all the new music I've been working on, there's been a huge musical maturation. With that said, there is a lot of influence of different genres, but to keep it simple, I'd say Adele meets One Republic, meets Gavin DeGraw, meets Amy Winehouse.

What's your song writing routine like?

This has evolved a ton over the years and still haven't really found a routine. My most creative moments are usually in the mornings, in the shower, and while on public transit around the city. Super random!!! I think on average these are the times my mind has the freedom to just think about anything. So, little melodies or song concepts might come to mind, or lyrics. Sometimes on a great day, all of these things come together at the same time. Little by little I build it. I don't force the song to come together in one day if it's not there. I let the idea "sit on the slow cooker" until it's ready (can be super quick or super long).

Are you playing any shows soon?

With the holidays approaching, no shows for the rest of 2018, but booking for 2019 already so all that information will be up on my website shortly. (https://www.DecemberRoseMusic.com)
