Is it possible to connect the Phone HD/2nd to IP telephony?
If so, any documentation available on how to do it?
An Icon or 220 can register to most SIP phone systems and then the Phone used for audio calling but the Phone is not supported as a standalone device.
3-4 years ago I asked LS Phone SIP compatibility question on one of LS seminars and was told that LS is looking into adding SIP support to their Phones. This would be great selling point because audio quality is very good but LS Phones can't be used as standalone devices to compete with other vendors IP conference phones...
Vlad, that is an excellent idea that does come up in customer conversations. I would recommend creating an idea here on community so that others can vote up (I will be the second voter).
How to Create an Idea or Feature Request
If the Phone HD/2nd Gen is conected to an Icon then you can go to the Icons admin page and you will find you can add the SIP information under SIP 2 (SIP 1 is used by the VC unit) so in efect you set it up as you would any new hand set on your system
Can you have an Icon (such as a 450 or 600) registered to both the lifesize cloud and via SIP to an IP Phone system (Cisco CallManager) to allow both video calls over lifesize cloud and voice extension or other outbound audio calls via call manager over a SIP trunk?
Absolutely. Lifesize cloud uses SIP1, leaving SIP2 available for registration to your sip provider.

I setup my callmanager server to add an icon 600 as a sip phone (advanced) and configured SIP2 on the ICON to register to my callmanager server. It registered just fine and I can make a call from either Cisco to Icon or vice versa. The phone or ICON will ring, but as soon as you pick the call up it drops and either on the Cisco side you will get a fast busy or on the ICON side you will get an unavailable message.
Any thoughts as to what I could be missing. I used the following links for reference for the setup:
Would you be ok with me making a case for you in our system? If so I can reach out to you through it and troubleshoot further via log analysis.
jim.trautman, try adding g.711 A-Law / U-law (or whatever audio codec cisco is using) to the top of the codec list.
Sounds like its not negotiating the correct codec.
Currently it is not possible to change the audio codec that the secondary SIP registrar uses but the default should be 711.
That would line up with what I am seeing, the only way I can get audio calls to/from Cisco Callmanager endpoints from Icon's SIP2 is if I setup the SIP phone in CUCM to use G.711 rather than our standard G.729 that we use for the Cisco phones. Uses much more bandwidth per call since it's not compressed unlike G.729 but it does work and won't break the LAN at still only 64k a call.
