Summary:                    incorrectly recognized codecs capabilities of
windows mobile 6 device
Description: 
Native voip/sip client (RTC/1.5) from windows mobile 6, reports in sdp,
that supports codecs:
siren,g722,alaw,ulaw,red 
asterisk this offer recognizes, but in further negotiation it interprets
as folowing capabilities:
peer - audio=0xc1c (ulaw|alaw|g726|ilbc|g726aal2)
combined - 0x400 (ilbc)
call fails, because ilbc is not supported in windows mobile and codec ilbc
isn't even offered in sdp from windows mobile device

iLBC is now correctly removed from combined codecs list, 
but why is g722 as 'unknown', even if g722 is shown in core show
translation and is enabled in peer config?  Codec Order  :
(g729:20,gsm:20,ilbc:30,g722:20)
