  1. Enabling SRTP and SIPS

    I am hoping to find a better solution than custom templates. T54W and T53W. it appears you have to not only turn on SRTP mode in users/options. but also have to write a custom template to enable TLS transport and enforce SRTP. Is there an easier way to flip 100+ phones to start using SRTP...

  2. Force phone template SRTP settings

    Hello all, We have SRTP Mode Enforced on our users. And this works perfectly for all phones. The only issue we encounter is when we log on an hotdesk. In our hotdesk template we have the SRTP mode set to enable, but when users logs on the hotdesk this settings get changed to enforced (due by...

    Hello ! When setting up an Hotdesk and configuring the RTP Encryption (SRTP) to Compulsory via the Phone Web admin, users cannot login anymore. Dialing *77*XXX* = Not Acceptable here error Of course it is possible to de-activate the SRTP encryption. But when logged-in user then calls an...

  5. SIP with TLS and SRTP

    Hello, We have trouble configuring TLS and SRTP on 3CX and Yealink T46S/G. Phones: TLS on the phones works but if we set SRTP to "Compulsory" it rings but we can not answer the phone. 3CX: If we enable TLS (in the SIP trunk) the entire SIP trunk stops working (with correct .pem file). I set...

  6. Template Support for Yealink T4x SIP over TLS & SRTP using Remote STUN

    Due to COVID-19 many of our employees are working from their home offices where it'd be impractical to deploy an SBC. The best solution is "Direct SIP (STUN Remote)". The catch is that all SIP signaling and RTP audio is sent in the clear for anyone to intercept. It's trivial to create a custom...

    yealink T46x DIRECT STUN TLS + SRTP no BLF

    Hi there, i tried to configure a yealink T46S without using SBC to connect to 3CX securely via DIRECT provisioning. I customized the template to use Port tcp/5061 and SRTP in compulsory-mode. This works fine. I also noticed that i need to configure the outbound proxy pointing to the 3cx...
