What channel type is the outgoing leg?

The inbound leg needs the variable switch_m_sdp set with the SDP of the
outbound leg at the time when the outbound leg is answered.
In the case of mod_verto a patch was added today to set that variable.  If
you are using something non-standard you will have to set that variable
yourself.
