Hi Mychaela,
The AMR capability works great with your drop-in MGW implementation, voice
quality improved a lot. I also tested the FR/EFR part earlier, which also
works as expected. CSD is definitely interesting, once I have at least two
CSD capable devices, I will give that a try as well. We already tried with
a Nokia MetroSite, and early next year I am planning to try with our
UltraSite setup at the museum as well. Would be nice to be able to send fax
on top of GSM :-)
The OML dialect we have in Osmocom now (called "nokia_site") despite its
name it supports old Nokia equipment up to Felxi EDGE, Multiradio and
Multiradio10 (on E1), if anyone else is interested, so OML support is not
limited to just the Nokia *Site family. Some of this stuff is still running
in less fortunate countries... Little bit of tweaking will likely needed,
but at least it is not a completely unknown part like AoIP.
Regards,
Csaba
