    We had a custom AGI script written by a freelancer here which needs a &quot;fix... Via a Asterisk AGI Python script initiated from a web page button, a queue agent can &quot;transfer a caller&quot; into a custom extension. The script works by seizing the active channel from the agent, sending the caller to the custom extension script, and releasing the agent to take another call. The problem is that when this is done, the queue agent typically gets the &quot;next possible call&quot; in their queue, instead of being placed into the last in line position which would be appropriate under our &quot;leastrecent&quot; ring strategy. After some investigation, we believe that the problem is that the agent&quot;s &quot;idle time&quot; timer is not being reset during the call-seizure-and-transfer script, thus Asterisk believes that agent to be idle far longer then is true.We are running the FreePBX v. distro with Asterisk 11.4.0.The contents of the Python script (/var/www/cgi-bin/ used to seize the call is:==========================================#!/usr/bin/pythonimport cgiimport sysimport reimport telnetlibMANAGER_HOST=&quot;;MANAGER_PORT=&quot;5038&quot;MANAGER_USER=&quot;xxxREDACTEDxxx&quot;MANAGER_PASSWORD=&quot;xxxREDACTEDxxx&quot;form = cgi.FieldStorage()print &quot;Content-Type: text/plain\n\n&quot;if &quot;callID&quot; not in form: print &quot;There is no callid&quot; sys.exit()if &quot;ptID&quot; not in form: print &quot;There is no ptid&quot; sys.exit()if &quot;agentID&quot; not in form: print &quot;There is no agentid&quot; sys.exit()callid = form.getvalue(&quot;callID&quot;)ptid = form.getvalue(&quot;ptID&quot;)agentid = form.getvalue(&quot;agentID&quot;)print &quot;Parse the request&quot;line = agentidmanager = telnetlib.Telnet(), MANAGER_PORT)manager.write(&quot;Action: login\n&quot;)manager.write(&quot;Username: %(MANAGER_USER)s\n&quot; %vars())manager.write(&quot;Secret: %(MANAGER_PASSWORD)s\n&quot; %vars())manager.write(&quot;Events: off\n\n&quot;)manager.write(&quot;Action: coreshowchannels\n\n&quot;)events = manager.read_until(&quot;CoreShowChannelsComplete&quot;).split(&quot;Event&quot;)data = 0for i in events: if;ConnectedLineNum: %(line)s&quot; %vars(), i): data = iif data == 0:print &quot;No channel up.&quot; sys.exit()result =;Channel: (.*)&quot;, data)channel = channelmanager.write(&quot;\n&quot;)manager.write(&quot;Action: redirect\n&quot;)manager.write(&quot;Channel: %(channel)s\n&quot; %vars())manager.write(&quot;Context: ivr\n&quot;)manager.write(&quot;Exten: s\n&quot;)manager.write(&quot;Priority: 1\n\n&quot;)manager.write(&quot;Action: setvar\n&quot;)manager.write(&quot;Channel: %(channel)s\n&quot; %vars())manager.write(&quot;Variable: callid\n&quot;)manager.write(&quot;Value: %(callid)s\n\n&quot; %vars())manager.write(&quot;Action: setvar\n&quot;)manager.write(&quot;Channel: %(channel)s\n&quot; %vars())manager.write(&quot;Variable: agentid\n&quot;)manager.write(&quot;Value: %(agentid)s\n\n&quot; %vars())manager.write(&quot;Action: setvar\n&quot;)manager.write(&quot;Channel: %(channel)s\n&quot; %vars())manager.write(&quot;Variable: ptid\n&quot;)manager.write(&quot;Value: %(ptid)s\n\n&quot; %vars())===============================================There are 2 other files/scripts used for this system (but they are for handling the call after &quot;transfer&quot;):/etc/asterisk/extensions_custom.conf/var/lib/asterisk/agi-bin/ivr.pyWe will provide access to copies of our other scripts as needed, but will cannot provide direct access to our PBX due to U.S. Federal privacy regulations.

    We are running Active Directory on Windows Server 2003 with about 40 agents. We recently have a situation where the agents are getting logged out with an error and we have to reboot the server before they will be able to get back in. This happens every couple of hours and we need someone to log in to our system and troubleshoot and help us determine what is causing this and find a solution. We do have a backup Active Directory that should be replicating but not sure if the errors are affecting this or not. We have been using the Active Directory with this set up for over 6 months with no issues and suddenly we have this issue. We need someone that can work with us during our hours of operation 7:30AM-5:00PM CST M-F to work on this. We need someone as quickly as possible (tomorrow morning if possible)

    Dear friends, I need someone with VOIP skills in order to finish an VOIP project. I will explain in few words what exactly this VOIP specialist should do: In this moment I have installed on my server software Free PBX, and I need to finish the configuration in this way: - I need to configurate FREE PBX for calling routes - for this I have 3 FXO operators connected to server using an FXO CARD TDM400 from Digium. - FXO CARD Digium is installed but need to be configurated - to make Trunks - and also calling routes , setup IVR am voice mail. - Regarding calling routes: I have 3 operators: Orange,Vodafone and a local fix provider (for Orange and Vodafone I&quot;m using premicell for connecting them with Digium Card) so for example if I&quot;m calling a orange number the pbx server should automatically use the Orange line,the same thing should be used for Vodafone line,if SIP account want to call a vodafone number,server should automatically use the vodafone line and so on... - Also the Voip system should be reachable from internet,because this client is not in the same location... Waiting your answer,Regards,R.

    To Configure Two Quintums, AXT-4800 Quintm And AFT-800

  • $1999 USD Oct 25, 2012

    Program should catch incoming/outgoing phone call events and start recording audio streams to the web server (through restful API provided) or memory or file. Phone call should not be interfered with this new functionality. Program should not be platform-specific and should work for, at least (but not limited to) android and iOS. One possible way to do this would be make a simultaneous call to a pre-configured machine using VOIP and put the three parties in a conference. It is upto the programmer(s) to implement a better technical solution, if possible.Working on this project requires solid understanding of how mobile telephony works. Knowledge of Objective C or Android Java is not at all required, nor is any experience in creating mobile apps mandatory.Development of mobile applications (Android and iOS) and web server (with rest-style services) are done separately and should not be part of this project. Please include details of requirements from telephony service providers or others so that we can facilitate these without any delay. Please include brief description of your technical solution so we can assess the scalability and maintenance costs of the solution for our future requirement.
