I've been experimenting Sipura SPA-2000 and I realised that it doesn't support G.729 in both lines simultaneously.. or be.. when I call to the first line it answersusing the preferred codec (G.729) and at the same time I call to the second line and it answer using G711a.
the same happened already in some ata's. if i remember correctly, it was due to lack of dsp hardware/cpu cycles, i.e., only one compression coded could be used at the same time. i consider it very bad.
