asterisk users - Dec 2010 - DAHDI on VMWARE

Hi gang,

            We are moving our computers from a cluster of physical machines
to a VMWARE server with virtual machines.  We investigated and are looking
to replace our TDM400P/TDM410P with AEX410P cards.  Can we run asterisk with
the DAHDI drivers from one of the Virtual machines or is DAHDI going to have
to be a native process on the "REAL" machine?

 

Thanks

Danny Nicholas

VMware has no type of "PCI-passthrough" feature that I'm aware of.
There are
virtualization environments that do, but the added overhead is going to make 
things extremely unreliable.

Could you update to the lastest version of DAHDI-linux and try:
]# modprobe wctdm24xxp debug=1

and give me the dmesg output?

I think the IO registers being in use is a side effect of a previous
failed load.  I just committed 9503 [1] to bypass that check.

Thanks,

Not an answer to your question, but why not externalize the telephony
interface with a SIP converter (like Patton SmartNodes or whatever you
trust (e.g. Positron sells PCI cards that should do the trick if you want
something "internal")).

A reasonable question.  I am presently communicating with this box using a
SIP trunk;  We just want to be able to use Copper for those occasions when
our Internet provider is down.
