[Asterisk-Users] Integration with a Siemens HiCom 150E / HiPath 3750

Hello again,

sorry for the delay in replying; I've been off for some weeks at a 
customer's offices and couldn't read my email at work...

Seems pretty much similar to what I intend to setup:


PSTN ------- HiCom ---------- * (+SIP cloud)
       PRI           S0-Bus 


Right now, the only free "indoor" boards provide a S0-Bus (8 ISDN 
lines), so I thought of using them instead of a PRI board.

Some questions about both scenarios, yours and mine:

    * is it possible to call VoIP from a PC to PSTN and vice versa?
    * is it possible to call VoIP from PSTN to an internal line? the 
idea behind this is to have a co-worker somewhere in the world and s/he 
could ring me on my desk from her/his PC, and vice versa.

It's a PRI.

Could you please provide some more information? Reading the "legacy 
integration" on the *-WiKi page doesn't clear things up too much...

You might want to discuss this off the list. I'd post the final 
conclusions when finished. In that case: Antwort auf Deutsch wäre auch 
gut ;)
