[asterisk-dev] stupid error in configuration

[Wojciech Puchar]

tried progressinband=yes, prematuremedia=no in sip.conf as found by 
google, prematuremedia=no changed "booooooo" into silence.

The problem consist only on that route:

SIP phone
asterisk
IAX2 trunk
asterisk
SIP phone

but not

SIP phone
asterisk
IAX2 trunk
asterisk
SIP trunk to polish operator.
