Nodejs implementing ESL Inline FreeSWITCH setting instructions

I. BACKGROUND notes:SIP server IP (Centos): 192.168.11.61, server IP (Windows): 192.168.11.19Second, the purpose:The SIP server (FreeSWITCH) can be accessed from the 192.168.11.19 via Nodejs's MODESL inline, enabling access to the status information of the SIPs server. Have seen a lot of documents before,SIP Server and inline programs are on a computer, this article provides a separate implementation of the way for everyone to refer to.

reality, the world there is no reason, no reason to hate, who will give you money for nothing, although I would like to find a sum of money. People's thoughts will always have such or such a disease, cured, all normal, not good, it seems to enter a vicious circle, and finally how to die do not know. Sometimes, I feel that I am also very ill, but I write articles to treat the disease.The life cycle platform of a program apeSlogan: Professional communication, career planning, face the reality, in

In-depth understanding of the equivalent series resistance (ESR) of capacitors, the role of multiple small capacitors in parallel to replace large electrolytic capacitors

, the more important of the other indicators is the equivalent series resistance (ESR). Some capacitors have a gold ribbon line printed with a large hollow letter "I", which indicates that the capacitor belongs to the LOWNBSP;ESR low loss capacitance. Some capacitors also have an ESR value (equivalent series resistance), the lower the ESR, the smaller the loss, the greater the output current, the higher the quality of the capacitor. The esr is the abbreviation for Equivalentseriesresistance, th

Proper configuration of PCB decoupling Capacitor

have the expected effect of noise filtering and is helpless in the face of stubborn electromagnetic noise. One reason for this is that the effect of capacitor leads on the bypass effect is ignored. As shown in the Circuit Model 4-7 of the actual capacitor, it is a series network consisting of an equivalent inductance (ESL), a capacitor and an equivalent resistance (ESR. The impedance of the ideal capacitor decreases with the increase of the frequency
