 As earlier referred following quote from their site

"DISCLAIMER: You might have to pay royalty fees to the G.729/723.1
patent holders for using their algorithm"

You have to pay royalty fee for using their algorithm and it does not
matter whether you are trans-coding or not however there is no restriction
to pay their royalty fee under testing / evaluation environment.

I do't think there is any restriction to use open source version when you
paid their roylity fee

Yes it is .   I do't think there is confilit between GPL license and g.729
patent fee
