Sip client - no audio

Hello. I have Openfire and Asterisk running in my PC. Openfire in Windows 7 and Asterisk in VM. I installed the SIP client in Server and Client Spark. The call works fine, but, no audio. There´s a way to fix this? I tested the SIP with another client, and worked fine.

Thanks.

Which version of spark do you use?
