Yes, it is strange - The gains are fine - users can hear the calls
perfectly at both ends, fax works fine etc etc - Only the recording is
odd.

I have tested this with IAX, and three different ISDN interfaces
(ISDN, Quad ISDN and Sangoma PRI) - All of them have the same symptom.

SIP to SIP is the only case that seems to work, almost as if the SIP
code is re-levelling the non-RTP stream. I think I need to try a Zap
to Zap forwarded call to see how that works...
