In my customer conversations, many people have told me that Microsoft Lync became their telephone system. They have more of a PBX. they use Lync 2010 for all their voice calls with Lync client hosted on XenDesktop 5.5 / 5.6 or VDI-in-a-Box and accessible from Citrix Receiver.
A partner in the Nordic countries said they've noticed this particular trend in the SMB space. last month, I spoke with IT managed services provider doing here in the United States, using Citrix Receiver for Mac 11.4 and Citrix Receiver for Windows. they installed the Plantronics Spokes ™ software on the VDA working with their Bluetooth headsets, and enjoy a good quality of voice over wireless network connections.
But I have also spoken with very large companies that make the change. for example, a major communications service provider eliminated telephone systems in all buildings at headquarters. (By the way, they indicated that the voice quality with XenDesktop 5.5 and Citrix Receiver 3.x is even better than their previous telephones!) And one of the largest suppliers of computer equipment were telling me all their new office buildings open without a PBX; they use Lync as their phone system.
Everything seems to support the bold claims that Microsoft did when Lync was launched in November 2010. The articles with titles such as The PBX era is over announced that Lync 2010 was "ready to replace corporate PBXs, generating savings by centralizing call control and other phone functions to reduce the number of devices that must be maintained."
other hand the call center market is still squarely in the camp PBX also, Dave Michels wrote in his article Microsoft Lync telephony. Ready to be a replacement PBX that "Lync demands quality, reliable and low-cost broadband, which are not always available. " So some customers prefer to use Lync in conjunction with their existing PBX, a mode which is actually facilitated by the integration features in Lync 2010.
XenDesktop provides full support for Lync today and additional optimizations are currently in beta. Some innovative features for Lync support in our shipping software currently include:
- Optimized-for-word of codec technology, with fast encoding and low bandwidth usage
- video compression Webcam in the Citrix Receiver for Windows and Linux, providing excellent efficiency of bandwidth and latency tolerance network
- jitter buffer in Citrix Receiver for Windows to ensure proper same when network latency is variable, and echo cancellation when using a microphone and speakers instead of headphones
- Audio plug-n-play
- routing audio device (eg, ringing can be directed to the speakers, but the voice of a headset)
- support for Polycom phones via USB isochronous USB redirection
- ICA transport multi-stream for QoS full support
- audio option UDP / RTP on XenDesktop VDI for a wide tolerance of network congestion and packet loss
- packet DSCP tagging for RTP packets (Layer 3)
- WMM marking for Wi-Fi
- Repeater Support Directorate for QoS and multi-stream ICA including UDP
