As stated in the subject, I am having a weird issues with testing tls and srtp on the Polycom vvx handsets. First I setup tls has recommended by previous post to the community, and now my acme packet SBC and the polycom handset are in harmony with communicating via tls.

 

The next step was to enable srtp, which seemes fairly simply compared to setting up tls, however although the invite/200ok SDPs between the SBC/phone request/asnwer with SRTP, the phone for some reason keeps sendingRTP.

 

The weird thing is if I should disable tls and allow only srtp, the SDPs are negotiated successfully and the phone intiates SRTP.

 

Any ideas?? I am currently running vvx400 on code 5.4.4. I also noticed some authentication errors in the app logs ONLy when the phone has both tls and srtp.

 

sample config

 

 

<reg
reg.1.address="6636"
reg.1.auth.password="************"
reg.1.auth.userId="6636"
reg.1.label="LabB Sec 6636"
reg.1.outboundProxy.address="************"
reg.1.outboundProxy.transport="TLS"
reg.1.outboundProxy.port="5061"
reg.1.server.1.address="********************"
reg.1.server.1.transport="TLS"
reg.1.server.1.port="5061"
reg.1.srtp.enable="1"
reg.1.srtp.offer="1"
reg.1.srtp.require="0"
reg.1.type="private"
reg.1.thirdPartyName=""
reg.1.linekeys="2" />

Resolution: Please check => here <=

 

and

 

Apr 23, 2013 Question: How can I setup SRTP / Secure RTP?

Resolution: Please check => here <=

 

And in addition I would set a NTP time:

And also use a currently supported software like UC Software 5.5.1 or 5.5.0 before or at least 5.4.5

Hello Jam,

as you did not post any logs please go ahead and escalated this.

In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.

If this is some sort of an Internet discounter please post your phone's MAC address so I can look up who would be able to support you.
