[Asterisk-Users] Failed to write frame when pressing 'o'

[Kevin]

I recently upgraded to the latest CVS and when  a caller presses 'o' in
voicemail, I get listed below.  I have searched the archive for a
suggestion and pared the sip.conf and extensions.conf to bare minimum to
duplicate this scenario.  Any suggestions?
