[Freeswitch-users] Cipher Suite not working

[Rex Lin (林昱頡)]

Currently we are using TLS for client/server communication, I would like to do debug using wireshark but got problem in decrypting.
I have seen Server Hello with only one single Cipher Suite of ECDHE, I’ve tried changing “vars” into AES256-SHA, though with the same result;
I wonder if anything had been missed or I’m in a wrong way?

Below is the detail, TKS for any advice.

Scenario: Client --> Kamailio PSTN --> External in FreeSWITCH
FreeSWITCH version: 1.6.20-37-987c9b9~64bit (-37-987c9b9 64bit)

----------------------------Wireshark debug----------------------------
private key: agent.pem
FreeSWITCH to Kamailio
Cipher Suite : TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xc014)

----------------------------vars.xml---------------------------------------
<X-PRE-PROCESS cmd="set" data="sip_tls_ciphers=AES256-SHA"/>


Best Regards,
Rex Lin
