[OpenSIPS-Users] phone not getting regsitered using TLS

[ideanet help]

Hi Karsten,
I thought the same initially but then looks like logs are saying:
Client used ciphers are:
        TLS_RSA_WITH_RC4_128_MD5
        TLS_RSA_WITH_RC4_128_SHA
and servers response is cipherSuite         TLS_RSA_WITH_RC4_128_SHA

isn't it?
