HDX and SIP

[Anonymous]

Hi,

just wondering.  Suppose i have a HDX.  Am i able to call a sip address with that HDX, without needing to fill in a sip server address in my sip settings?

Thx

A SIP server is required.....

Ken,

Sorry, but just checked - SIP calls without SIP server are possible. Both <EP IP Address> and <Name>@<EP IP Address> formats can be used.

WBR,

Mike,  technically you are correct, however a server goes a long way in ensuring the call will actually connect.  With most networks there are private IP addresses behind firewalls that require NAT.  Now a SIP call could get through assuming the device doing the NAT is smart enough to replace all the IP addresses in the payload of the packet and that scenario will probably fail without an SBC.

So yes it will connect on a simple network, however most companies do not have a simple network. So for ease of use, flexibility, connectivity etc., the server is a key player.

Ken,

I agree with you, it's possible under some simple conditions.

WBR,

Hi, thx for these replies.  So we need a sip server.  Actually i have one, MS Lync.  But this one can only be authenticated upon by people in our own Windows domain (well, you can create trusts between AD domains, but that's not the goal here).  Besides that, i also found out that content shared from a Lync (2010) client is not visible on the Polycom client.  So this might not be the best choice?  Any product in the Polycom range which we can use for that (we have CMA, RMX, VBP(ST)?

Polycom also offers integration services from our 'Professional Services'  division.  -link below -

Polycom provides support for Polycom solution components only. Additional services for supported third-party UC environments integrated with Polycom solutions are available from Polycom Global Services and certified partners. These services are intended to help customers successfully design, deploy, optimize, and manage Polycom visual communication within their third-party UC environments. If you want to deploy Polycom Conferencing for Outlook or Microsoft Lync Server, you need to contact Polycom Services or contact your local Polycom representative for more information.

An 'RTV' license "MicroSoft Real-Time Video" is needed on the HDX. 

Polycom HDX systems, RealPresence Group Series systems, and RealPresence Collaboration Server conferencing bridges include support for Microsoft’s RTV media codec and Lync multiparty calling.

The H.263 codec has been deprecated for Lync Server 2013, and RTV support is required to deploy HDX systems, RealPresence Group Series systems, and RealPresence Collaboration Server conference platforms with Lync Server 2013.

Polycom HDX systems and RealPresence Group Series systems now support all RTV video resolutions for peer-to-peer Lync video calls and multi-party video conferences that you host on the Lync Audio video AVMCU. You do need to obtain the RTV option key:



To support Lync conferencing.



To support RTV video resolutions beyond CIF resolution using H.263 codec when registering with Lync Server 2010 (The H.263 codec has been deprecated for Lync Server 2013).



RTV is supported on a RealPresence Collaboration Server system only if you have an MPMx card
