Logicwrath Posted January 23, 2018 Report Posted January 23, 2018 Hello, I have a specific client interested in using SRTP to encrypt voice calls. I am trying to test these features out but I am running into some issues. Here is what I have done so far on my Yealink T46S. 1. Edited device in advanced call flows. Under the Audio tab I set Secure RTP to SRTP. This erases your advanced provisioner profile for the device. 2. In the Advanced Provisioner under Lines I made sure that RTP Encryption (SRTP) was set to Enabled. 3. In the Advanced Provisioner under Lines I made sure that the Primary Address was set to secure-us-east.p.zswitch.net. 4. In the phones web interface under Account -> Advanced I manually set RTP Encryption (SRTP) to "Compulsory". I was not able to place outbound calls without setting this manually. I am able to place outbound calls and lock shows up on my Yealink phone indicating that the call is encrypted. However, I am seeing some major issues and I was hoping to get some assistance. 1. BLF is not working. The BLF keys are showing a RED X. 2. I am not able to receive inbound calls. The Hangup Cause is "RECOVERY_ON_TIMER_EXPIRE" with a hangup code of "sip:408" Any suggestions on how I could get this working?
Logicwrath Posted January 23, 2018 Author Report Posted January 23, 2018 I started testing a Polycom VVX 411 as well and I am seeing the same errors and unable to receive calls but I can send them.

IT works for me Using Advanced Call Flows - Device - Audio - Secure RTP (Select SRTP) Then in Advanced Provisioner for the Device Config - Lines - Scroll to the Bottom of " 1 " In Advanced - Make sure the RTP Encruption (SRTP) is enabled. Restart the phone (if you made a change versus building new) From what I can tell. That is all now, as of Version 4.3-11 The only thing different I can tell, is that there is a "Lock" on the Yealink phones, AFTER the call is established.
