• 'Distinctive Ring on Yealink Phones'

A common query for people implementing IP based phone systems is how to have a phone ring differently for internal (from within the office) and external (from the PSTN) calls. To do this you'll need two things; a phones that supports this - here we're using Yealink phones, and a VoIP server that supports the "Alert-info" header - many do such as the popular open source solutions Asterisk and FreeSWITCH. Other than that it's all pretty straight forward.

Firstly we will configure the Yealink phone. To do this go to the "Phone" tab and then to the "Ring" page under that.

Once there add an entry into the first set of boxes. Under "Internal Ringer Text" choose a short descriptive name for the ring, I've called it "Internal" as I'm going to use it to change the ringer for internal calls. Under "Internal Ringer File" select the ring that you would like to use. That's it as far as the Yealink phone configuration goes.

Configuring the VoIP PBX differs depending on the SIP server you are using. For Asterisk you need to set a alertinfo to the extension or incoming rule configuration

• 'call completion'

بعد از شماره گیری یک داخلی، اگر شماره مقصد اشغال باشد تماس گیرنده در صورت تمایل می تواند تماس را callback کند. یعنی به طور اتوماتیک بعد از آزاد شدن مقصد، تماس برقرار شود. به این ویژگی completion گفته می شود.

Call Completion که به طورکلی مخفف Call Completion Supplementary Services (CCSS) می باشد به عنوان یک قابیلیت جدید درasterisk 1.8 معرفی شده است ودر آخرین توزیع freepbx به عنوان یک optionدر تعریف داخلی مورد استفاده قرار می گیرد.

completion در بعضی از ipphoneمثل yealink به عنوان یک قابلیت و feature تعریف شده است و می توان آن را فعال کرد. اما شما نیز می توانید با dialplan نویسی این قابلیت را فعال کنید.

In this file /var/www/admin/modules/core/functions.inc.php add in line 262

$output .= "cc_agent_policy=generic\n";
$output .= "cc_monitor_policy=generic\n"

Add this lines to extensions_custom.conf

[phone_call]
exten => s,1,CallCompletionRequest()
exten => s,n,playback(beep)
exten => s,n,Hangup()

[phone_cancel]
exten => s,1,CallCompletionCancel()
exten => s,n,playback(beep)
exten => s,n,Hangup()

in web add two extention_custom for above context

add two feature code with 'برنامه متفرقه'
