Hi Alejandro!

Just to answer your question clearly: Yes, GSM would be a working option for
your scenario.

If you ever need G711 to connect to ISDN the transcoding should be no
problem for a P4 class system and for example 30 ISDN-Lines.

But what the others want to say is that buying new phones just to avoid
paying for G729 licenses may not be a good idea as the licenses are quite
cheap (US$10 for every transcoding you USE at the same time, NOT for every
phone you have).

I hope that answers your question.

Christian
