Description:Call from SRTP SIP-Phone into:

exten => 4001,1,Answer
exten => 4001,n,MusicOnHold()
-->OK, get Moh with SRTP.

exten => 4002,1,MusicOnHold()
-->Not ok: Get Error:

So calling a app that do not make a Answer itself (like MusicOnHold), you get this error. Surely there are also other circumstances (early media?) where RTP starts moving to the phone without a complete answer is done.
