Due to the need of VoIP projects at work, I recently got in close contact with the asterisk engineering code. As for the great Position and Role of Asterisk in VoIP, I will not talk about it. Please refer to the previous article: astersik + radius simple strategy.

With the decrease in the cost of using VoIP, family and individual users are receiving more and more requests for using Vonage (or other similar products).

incorrect.A: the reason for this problem is that the zaptel driver version does not match the asterisk version. Asterisk and zaptel are usually released in pairs, and there is a ing between versions. Whether zaptel and Asterisk of different versions can be used together requires careful verification. Once a caller identification problem occurs, the simplest and
