Architecture and software development

Hi Patrick

I have a question about the architecture and software development today. I've prepared an image(Dect-labv1.0.jpg) on the 3 scenarios in which I work, basically would be the following:

1) DECT Terminals Connected to Asterisk This lab works perfectly, with the latest versions that have posted until today.

2) Connect a PC card pcmcia Dosh & Amand like a Portable Part (PP) You can use a pc with a pcmcia and associate as a PP to asterisk server-Dect for make calls with other users?, I have questions / problems as a register from the laptop to asterix

3) Linking two Asterisk servers using the DECT protocol to share calls between PBXs

It is possible this configuration?

Thank you very much for your work Greetings
