[Serusers] 3-way calling

[ron]

Hi,

Can I do this on ser, using a sip phone(eyebeam), i'll call another sip phone,
when call is connected i'll put him on hold and dial another sip phone, when
it's connected, i'll press the conference, the 3 should be able to talk.

I tested it but only the one on the middle can hear voice from each other, but
both ends cannot hear themselves.

Is there a special module for this, what do i need to add on my ser.cfg?

Regards,
Ron
