According to these sites:
http://www.quintum.com/support/xplatform/ivr_acct/webhelp/Disconnect_Cause_Codes.htm
http://www.cisco.com/en/US/docs/ios/11_0/debug/command/reference/disdn.html

Cause code 50 is:
Requested facility not subscribed - The remote equipment supports the 
requested supplementary service by subscription only.

I don't know what that really means, sorry. It could be a setting with 
your switchtype or pridialplan in chan_dahdi.conf. Or, it could be 
something's not set up right on the telco side.
