Hi folks,

I was doing the compilation of libpri, dhadi and asterisk, everything is fine and It´s running successfully, I´m new in the VOIP´s world, but for that reason we are here isn’t. I would like to ask assistance in one doubt that I have, my server is running in my LAN, and I have two hosts with the zoiper soft phone configured, I was able to proceed with the hello world in the documentation, then I proceed to do extension configuration and this is what I did, please see files below

extension.conf

[from-internal]
exten = 100,1,Answer()
same = n,Wait(1)
same = n,Playback(hello-world)
same = n,Hangup()

[my-phones]
exten => 6001,1,Dial(SIP/6001)
exten => 6002,1,Dial(SIP/6002)
exten => 6003,1,Dial(SIP/6003)

sip.conf

[from-internal]
exten = 100,1,Answer()
same = n,Wait(1)
same = n,Playback(hello-world)
same = n,Hangup()

[my-phones]
exten => 6001,1,Dial(SIP/6001)
exten => 6002,1,Dial(SIP/6002)
exten => 6003,1,Dial(SIP/6003)
chapo@debian:~$ cat /etc/asterisk/sip.conf
[general]
port = 5060
bindaddr = 0.0.0.0
context=others

[6001]
type=friend
context=my-phones
host=dynamic
secret=***************

[6002]
type=friend
context=my-phones
host=dynamic
secret=**************

[6003]
type=friend
context=my-phones
host=dynamic
secret=*********************

Now doing this im able to dial to the 3 extension with no issue, but when I tried to establish the conversation the voice isn’t sound, all my WS have the zoiper client installed and configured, dial is going well but no voice sound

any advice ?

Assuming certain cut and paste errors it looks OK, but not current best practice. from-internal is no longer reachable.

An inbound firewall could be blocking RTP.
