 I saw this too - rtp udp stream to idle SIP phone (checked with tcpdump), 
then garbled audio when user listens to incoming/ougoing call. No 
transfers, no load - very small pbx (40 users total), simple SIP calls 
through Sangoma PRI Zap channels.
 Seems like asterisk do not properly hangup channels when network is 
unreliable to the phone.
