![]() ![]() It comes in both 32-bit and 64-bit downloads. Previous versions of the OS shouldn't be a problem with Windows 8 and Windows 7 having been tested. X-Lite can be used on a computer running Windows 11 or Windows 10. What version of Windows can X-Lite run on? 5.51 is the latest version last time we checked. Download and installation of this software is free, however other similar programs are available from modem and telephony software which may have what you need. X-Lite is a restricted version of commercial software, often called freemium which requires you to pay a license fee to unlock additional features which are not accessible with the free version. ![]() Zero-Touch Configuration of your USB headset or other audio/video devices.Standard-definition voice and video calling.Open Standards and Session Initiated Protocol (SIP) based call signaling allows X-Lite to work with a wide number of networks.Instant messaging and presence using SIP SIMPLE.Comprehensive Contact list, including detailed calls lists and history.X-Lite is actually a stripped free version of the commercial products created by the same developer. It also supports file transfers and contact status notifications.Ĭalls can be setup by utilizing different DTMF methods, that is signaling digits between user agent servers and user agent clients. X-Lite has a number of configuration options that can alert you to incoming calls, configure a headset or speakerphone mode, use different audio codecs for calls and enable video calls used H.263 codecs. With this application, you can connect to your account, access and setup your voicemail box and setup transport. Some of the features include voicemail, USB headset and other audio device support and instant messaging user SIP SIMPLE. The program relies on open protocols and the user's access to a functioning SIP account. X-Lite is a freeware voice-over-IP telephone software application which provides for free standard-definition calling over SIP. This is because it is the "best quality" CODEC that can be negotiated.Desktop softphone application for Windows with Voice Over IP protocol as an alternative to traditional landline telephone. So, as long as you have the G722 CODEC enabled in the Call Manager service parameter, have enabled G.722 advertisement in the Enterprise Parameters, and have phones that are allowed to advertise G.722 - then you will find that two G722-capable phones that are talking to each other in a G.711 region will actually use G.722. Now, G.722 has the same bandwidth requirements that G.711 has. When this CODEC is specified and the inter-region Link Loss Type is set to “lossy” the iLBC CODEC is forced. This setting identifies the best quality (highest bandwidth) CODEC that can be negotiated. ![]() The CODEC setting for a region or inter-region communication does not specify the exact CODEC that will be chosen. From the CUCM/Region perspective, CODEC selection is derived from the intersection of CODECs supported by all entities involved in the media stream. This gets into that "choose the best" discussion I had in my original follow up. This assumes you decide to invest money into supporting the Counterpath product that you enjoy using and purchase the X-Lite pro.Īctually, you won't need to create a new region for G.722 CODEC, your G.711 regions will support this (assuming you have CM service params and enterprise params set to the defaults). Not sure how this plays with X-Lite as a client, but it may mean you will need to set a preference on CODEC choices. Also, with respect to SIP trunks, CUCM relies on the CODEC preferences in the SDP provided by the SIP-UA. It doesn't have an immediate impact on your scenario, but it is something to keep in mind. It is a subtle difference, but a difference nonetheless. Keep in mind that when CUCM refers to the audio CODEC they really mean the "best CODEC" not the "only CODEC supported". You only other alternative is to put X-Lite in a special device pool which has a special region that allows inter-region use of the G.711 CODEC. If you go with the X-Lite pro, you can get the G.729 CODEC supported in the client and then you should be able complete your calls successfully. In other words, your calls are failing for the reasons you have already identified. Because you have configured your inter-region voice CODEC to use G.729, the phones in the different regions will be unable to stand up the media stream. ![]()
