Hi,

maybe your RTP stream is not getting through the asterisk box due to 
"canreinvite=yes" setting in your SIP profile?

What is result of the following test in your dialplan?

exten => 123,1,NoOp(***INCOMING CALL***)
exten => 123,n,Set(CHANNEL(language)=en)
exten => 123,n,Answer()
exten => 123,n,Read(CONFNO,conf-getconfno,4)
exten => 123,n,Playback(conf-enteringno)
exten => 123,n,SayDigits(${CONFNO})
exten => 123,n,Hangup


Cheers
