Hi Michael,

I understand, so do I need to adjust settings in sip_internal?

Thanks

it sounds like one side is configured to require srtp but the other side is not?

Hi,

I have been trying to build my first production FreeSWITCH system, and am currently stuck on the following.

When I try and dial the 5000 demo system, I am getting:

switch_core_media.c:3455 Crypto not negotiated but required.

I am using the Zoiper software client under Linux.

Thanks in advance
