Information about ASTERISK

Good afternoon to everyone :

My name is Pablo, I’m new in this site and I’m very interested to know about this community.
I’m the CEO of a company and I would like to know if there is any way to do the following things:

  1. Establish communications by cellphone application (that should be private). I want to know if there is any possibility to make it encrypted for voice and video conference.

  2. Is there any possibility of limiting access to the application with the IMEI of the cellphones ?

Well, I will be waiting for your posts !
Thanks in advance.

Encrypted audio calls using Asterisk can be done with TLS, here is a tutorial … g+Tutorial.

limiting access to the application with the IMEI of the cellphone ,it can be easily developed by any android developer, It is just read the IMEI of the phone against a DB and if found allow else denied

TLS only encrypts the signalling. On SIP, it is a pre-requesite to the use of SRTP, which encrypts the media. Encryption is hop by hop.

I don’t understand the IMEI question. As far as I know IMEI is not normally passed beyond the HLR in GSM networks, so wouldn’t be available to the other party.
