[cisco-voip] right fax sr140 transmission errors

[Scott Voll]

Just to come full circle......

right fax does have ECM and V.34 settings.  But that was not the problem.
 after a night of fun.... 4pm to 4am..... with both right fax support and
TAC.  we found that we had to enable T.38 corporate wide, which included
both VGWs and all our VG224s.

But that still was not the issue.  we had network issues with vmware.  we
could literally go 15 seconds with no packets.  we moved the right fax VM
to it's own virtual Nic which fixed that issue. and since then.... we seem
to be running clean.

Anyone know how they setup there VM Servers with multiple nics?  do you
team them on VM host and on the network Switch?

TIA

Scott
