Hello! Please help configure srtp between Polycom VVX 400 (version 5.9.6.2327) and FreePBX (version 15). My torment has been going on for 2 weeks. SIP TLS registration is successful. The call and conversation without encryption is successful, when srtp is turned on, nothing works. Certificate generated according to the instructions: https://community.polycom.com/t5/VoIP-SIP-Phones/FAQ-How-can-I-setup-a-TLS-connection-for-SIP-signal... .I really count on your help, thank you very much! Сonfiguration and log files are attached.

Hello @Grigory ,

Your post ended up in the Spam Filter so I moved this here.

 

I see that you are based in Russia and the hardware we sell in Russia does comply with government regulations and therefore does not support SRTP.

Best Regards

Steffen Baier

Thank you for deleting my message from spam!

 

Why not? The WEB menu has an option to enable SRTP. And config has SRTP too.

Hello @Grigory ,

 

simply to my knowledge as the Russian government requires us to.

 

A simple SIP trace at debug should show if a Crypto is offered or not.

 

Please utilize the quoted FAQ to troubleshoot this.

 

If you are still convinced that this should work (as I know it will not for a Russian SKU) please open a support ticket.


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

End Customers are usually unable to open a ticket directly with Poly support. Available End User Poly services offerings are detailed here

If this is some sort of an Internet discounter providing your MAC address or your Poly devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Poly device from.

If the unit is no longer within the warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here


Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Steffen Baier

Hello! My phone MAC: 0004F280D6F0

I think that if SIP TLS works, then SRTP should work too.

 

This is the Polycom log file when an incoming call is made with SRTP:

Hello @Grigory ,

 

Your Mac shows as a VX 400,POE,RU (P/N: 2200-46157-114) aka Russia.

 

Poly can sell phones in Russia that can:

 

  • Encrypt the SIP Traffic using TLS
  • disable SRTP in the factory as the license we hold for Russia does not allow us to encrypt the Media Stream

The above explains why you can use TLS but not SRTP. This is the same if the phone would be used for Skype for Business.

 

The above is a requirement by the Russian Government.

 

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Hello @Grigory ,

 

just to add to your latest comment about the reply received from our support team. I had already outlined the following:

 

  • In order to raise a support ticket, you need to work with your Poly reseller as they may need to do this for you.

    End Customers are usually unable to open a ticket directly with Poly support. Available End User Poly services offerings are detailed here

 

Checking the supplied Mac shows the phone was sold 29/06/2013 via OCS Distribution Deutschland AG.

 

Therefore any support we can officially provide would be via PPI.

 

As I made it clear why this is not working please accept this as a solution.
