We have a large number of IP450 phones working (more or less!) with Lync 2010, though we're having issues with voicemail. Per phone config includes this:
Has anyone had any similar experience or fix? Any suggestions welcome.
voice.codecPref.G7221.24kbps 5 Set this parameter to 5 and voice.codecPref.G7221.32kbps to 0 to ensure users can hear audio when accessing voicemail
In addition as mentioned in the FAQ always post your current Software used.
If abvoe does not help you please contact your Polycom reseller for further support.
Turns out we did RTFM, heres the lyncshared config (using on UM 4.0.2B):
<lyncShared> <TLS sec.TLS.customCaCert.1="-----BEGIN CERTIFICATE-----<snip>-----END CERTIFICATE-----" sec.TLS.profileSelection.SIP="ApplicationProfile1"></TLS> <features feature.presence.enabled="1" feature.messaging.enabled="1" /> <SRTP sec.srtp.require="1" sec.srtp.key.lifetime="2^31" sec.srtp.mki.enabled="1" sec.srtp.mki.length="1" sec.srtp.holdWithNewKey="0" sec.srtp.resumeWithNewKey="0" /> <signalling voIpProt.SIP.mtls.enable="0" voIpProt.server.1.specialInterop="lync2010" voIpProt.server.1.address="lyncserver.mydomain" voIpProt.server.1.transport="TLS" tcpIpApp.keepalive.tcp.sip.tls.enable="1" voIpProt.SIP.IM.autoAnswerDelay="40" voIpProt.SIP.allowTransferOnProceeding="0" /> <voice.codecPref voice.codecPref.G7221.24kbps="5" voice.codecPref.G7221.32kbps="0" /> <voice.audioProfile voice.audioProfile.G7221.24kbps.payloadType="112" /><video.iFrame video.iFrame.delay="2" /> <profile dialplan.1.digitmap="x.TRR;phone-context=ourcontextR" /></lyncShared>
The <voice.codecPref voice.codecPref.G7221.24kbps="5" voice.codecPref.G7221.32kbps="0" /> has been in from the start.
Any other tips?
I would suggest your check the phone logs and work with your Polycom reseller in order to raise a ticket with Polycom support.
The community does not enable me, as a Polycom employee, to troubleshoot your installation for free.
The LYNC deployment works with the current release with basic functionality including voicemail so it must be something within your environment or configuration.
Again, using lync on pc works, using a cx500 works, using a cx600 works, the config is in line with the docs. The IP450s do not work.
You say "The LYNC deployment works with the current release with basic functionality including voicemail so it must be something within your environment or configuration." Does this mean that the Polycom IP450 running the latest UC software officially works with Lync 2010 voicemail? For the 4.0.1 doc attached to the post you linked to earlier, the only thing in the "basic support" list which is close to VM is "VM message waiting"
I went down the "contact supplier and get them to raise a ticket" for the last issue and that was a dead end, with the reseller getting a similar response. We have a case open with Microsoft as well, hopefully they will be more keen on helping.
Hello The Fish,
the current UCS 4.0.x releases are not Microsoft certified and therefore have limitations like Audio Gateways etc.
In a normal LYNC environment calls and voicemail work ( that is why that parameter highlighted in my original post was added) but individual solutions may have issues as you experienced.

Other community members may reply or help you but as a Polycom employee I am unable to troubleshoot your issue for free.
Raising a ticket via your reseller and providing the information our tier 2 team requests should get your setup working.
Feel free to contact me via the Forum internal mail with your previous Polycom service ticket reference starting with 1- in order for me to check who you dealt with and what problem was reported.
I'm still waiting for the reseller to get back to me with case number, but now have tested with a cx600 from another office - works perfectly. It seems theres something the 450s cant cope with. Again, anyone with ideas or suggestions, please chip in!
the test with the cx600 is not comparable as it is a completely different device.
