Review on You mobile phone as VoIP Terminal

First of all, before exploring the possibilities, we must take into account the connection of the mobile to the Internet, that is if we connect
by 3G/4G/GPRS

Internet calls do not consume excessive traffic, but it must be taken into account as well as the "delays" or latency of the network, so that
with voIP applications that support high compression codecs we save a lot of bandwidth of data usage. In other words, it will work much better
to better be our connection, being in WiFi more than enough for a high quality and in GPRS can manifest some problems of sound quality.

The first candidate is WhatsApp naturally. Now it allows voice calls to other WhatsApp users. The biggest drawbacks are the absence of being
able to call non-Whatsapp users (for example, a phone number or a user that uses Gtalk).
Another drawback is that the application itself is more messaging oriented, so the speed dialing of a recipient is not as comfortable as
normally occurs in the phonebook of "normal" phone numbers.
Yes, the application and subscription is already completely free, but that is the same as the others.

The second candidate is Skype, based on a software development that consumes a high level of CPU process, we will not be able to use it in low
power terminals since sometimes it will not even open the application. Battery consumption in the mobile is another factor to consider.
It allows free calls to other Skype users and to traditional phone numbers at an extra cost. It also allows us if we associate or buy a Skype
number or DiD to receive calls.

Its use is simple and convenient, compared to the two previous options.

SIPHON is very similar to SIPDROID but developed in C and initially for Simbian, that if, being developed in C and not JAVA, the software
performance is somewhat superior and the great advantage is that it includes the high compression g729 codec, with which the consumption of data
width will be only 26 - 32 Kbps !!!
As SIPDROID is a SIP client, this means that you can register with Zonnox or any other SIP provider and therefore you can interconnect with
other networks and systems (conventional telephony, Skype users, Gtalk, Cisco Jabber, etc.) that the provider enables. .

ZOIPER offers softphone for most platforms, including MS Windows, Linux, Mac, Android, and have two brands, one free and one non-free that add
several features as well as g729 codec.

With either SIPDROID or SIPHON or Zoiper you can request "normal" telephone numbering from your SIP provider, Zonnox can provide your own
standard numbering in Spain and other countries to receive your calls.
