oh this works now, good to know. Does anybody know if this feature works
with any gsm interface too?

sending SMS through the PBX isn't possible or why can't you connect
behind the PBX?

You write "assume". Why does it listen to? Of course it sees everything
on the bus. But as you didn't mentioned anything, I think the other DDIs
are reaching the expected destination through the nomal PBX?

I think this is for voice/fax/data services only. Sending SMS is more a
Abfallprodukt of network commands in my opinion.

No, idea, I guess you have to wait for HSP :-)
