Last week we had started a series de free software recommendations for every moment of the day. Of course, this is an absolutely arbitrary classification on my part since as far as I know, unless a parental control program is used, there are no time limits for the use of applications.
The afternoon, according to productivity specialists, it is a good time for meetings, phone calls and reading emails electronic
free software for the afternoon
Communicate with other people by voice and audio.
Blink
SIP, which stands for Session Initiation Protocol, is a protocol used to initiate, maintain, monitor, and terminate communication sessions. It is used in telephone calls over the Internet, as well as private IP telephony systems, as well as in mobile telephone calls over LTE (VoLTE).
Blink can be used with payment services based on the SIP protocol, on a local network using Bonjour (On Apple devices) or for free using SIP2SIP.
The program allows communication through image, video and chatt using the following protocols:
- MSRP: It is a protocol for the transmission of messages during the course of a session.
- OTR: It is a protocol for end-to-end encryption for instant messaging conversations.
- SIMPLE: It is a SIP-based protocol for instant messaging.
- XCAP: It is a protocol used by messaging clients to write, modify, and read application configuration data stored in XML format on a server.
It can also be used to transfer files securely monitoring the progress of shipping and receiving.
Two other modes of communication are screen sharing and multi-conference.

Written communication
Although they have given him dead many times, email is still alive and widely used as a marketing tool. Many, especially since the popularization of the Yahoo! and Google, prefer to use the web interface, however, there is a lot to be said for email clients.
Some of the advantages are that of being able to see all the accounts in the same window, customize the user interface or add PGP encryption keys.
For convenience, most Linux email client users use Thunderbird. It is an excellent tool and it comes pre-installed. But, the options do not end there.
Claws Mail
If you use a GTK-based desktop like GNOME, Mate, Cinnamon or XFCE and are looking to consume less resources of those used by Thunderbird, keep in mind this program which in addition to sending and receiving emails acts as a news reader.
In case you need additional features like calendar or automatic address aggregator you can get it through its plugins.
I don't want to end the article without mentioning K-9 mail, an application for Android that in a short time will be the base of the mobile version of Thunderbird.
