When writing SQL statements, we try to use a specific column name to replace the asterisk (*). Although the efficiency is negligible, writing is actually another realm. For example, many times we write like this: When writing SQL statements, we try to use a specific column name to replace the asterisk (*). Although the efficiency is negligible, writing is actually another realm. For example, many times we

The network structure is as follows:Asterisk (192.168.1.99) That is to say, both Asterisk and SIP terminals are behind Nat. The solution is as follows:1. Modify the SIP Extension settings in the SIP _. conf file.Nat = YesQualify = yes; it seems this item is not requiredExternip = 55.66.77.88; change to match our external IP addressLocalnet = 192.168.1.0/255.255.255.0; change to match our network settings 3. Modify in RTP. confRtpstart = 1, 10000Rtpe

PHP uses the regular expression to replace the display function with an asterisk (*) for the four digits in the middle of the phone number. Because the customer needs to maintain privacy, the mobile phone number cannot be completely displayed on the website, but it cannot be displayed, so many websites think of display but not complete display, in fact, it is very easy to use the asterisk to replace the d

When I was a beginner in php, I knew to use the replacement function to replace the specified number. But we need to simply replace the specified position. Below I will introduce several examples to show the asterisk. When I was a beginner in php, I knew to use the replacement function to replace the specified number.

In the definition, a function adds a star number before a parameter to convert multiple parameters passed in into an object, tuples, or dictionary, it can be said that these parameter values are collected and the function is defined. by adding a star number before the parameter, the passed parameters are converted into an object, tuples, or dictionary, it can be said that these parameter values are collected. Adding an asterisk before the parameter

This article mainly introduces the PHP implementation of mobile phone number middle four with an asterisk (*) hidden custom function sharing, which is a more commonly used features, the need for friends can refer to the followingPHP shielded phone number middle four bits:Method 1:function Hidtel ($phone) {$IsWhat = Preg_match ('/(0[0-9]{2,3}[\-]?[ 2-9][0-9]{6,7}[\-]? [0-9]?) /I ', $phone); Fixed telephoneif ($IsWhat = = 1) {return Preg_replace ('/(0[0

Is the call flowchart of Asterisk: We use the call process of SIP as an example to describe the call process of other channels. The call process (incoming) is as follows: Do_monitor-> sipsock_read-> handle_request-> handle_request_invite-> sip_new/ast_pbx_start-> pbx_thread->__ ast_pbx_run -> Ast_spawn_extension-> pbx_extension_helper-> pbx_exec-> execute dialplan When the chan_sip module is loaded, an independent listening thread do_monitor is starte

Here I will attempt to describe how to make N-way CILS from 2-way CILS. First, you need trunk version of Asterisk. All work done by two applications: meetme and channelredirect. You need zaptel driver to have meetme working. Question:For Asterisk 1.4 do wee need to replace 'channelredirect' as used below with 'managerredirect' as in bug/patch 6508? Here is dialplan example: [Default]Exten => _ XXX, 1, set

Sneak in, see the snow forum above saw someone released a "Win7 Asterisk password Detection Tool", found that "there is a little" small use.The reason is not very useful: This program's ability is quite limited, can only see a portion of the software is not high-security password box inside the program,If you want to take it to see the QQ password, for granted, it is impossible.The program uses a very old technique to get the contents of another proce

Preface Ask what is the use of this system. Previously said to do a SIP system server to test IP recorder applications. Before using the Raspberry Pi has been able to run smoothly. Next use Beaglebone-black to realize this function.
