So you are saying that I should also install these other two applications (
are they applications ? excuse me , but i'm not familiar with this and I dit
not quite undestood what you ment to say)
So, in your scenario with SER is the session established OK? In other words,
is the call established and lasts on both phones for more than 30s (or
more), or less than that: the callee picks up, but this is never perceived
No the session is not established with SER (it gives me busy tone) ;
without SER (from the AS directly to the HT), the phone rings more than 30
sec , but when it is picked-up ... nothing.
And this is my problem ,that with SER the phone doesn't ring and I do not
know how to make this happen from the ser config file.
If it helps , here is the dial-peer from the AS router to send the packages
dial-peer voice xxxxx voip
description tech support
voice-class codec 11
session protocol sipv2
session target ipv4:193.226.xxx.xxx ----> the ip of the computer with
-I'm sure that this dial-peer is corect because , as i said before , it
worked with a hardware SipServer.
As last resort, do a network sniffing on the SER box and send it over.
This will take some time , because I will have to install Ethereal on linux.
