[cisco-voip] Cisco Fax Server/ Resource Unavailable / MGCP H323

Tue Mar 11 11:10:29 EDT 2008

We have both fax passthrough and fax relay working at a site using the mgcp
config I forwarded previously.  There are some gotchas, like having to
downspeed the faxes and disabling ECM occasionally, but only in rare
situations.  And I think those are issues associated to fax passthrough in
general.

 I have both Xmeduis Fax server and ATA's working over the same PRI's at my
main site.  

But I'm also using H323 gateway so I have a little more granulaity.

Hi Kalle,

regarding the MGCP configuration check my previous email. I don´t think that
you can use ATA´s and FaxServer coexistent on one gateway. You would have to
configure two faxprotocols. Fax passthrough and T.38. I don´t think that it
is possible. Someone please correct me, if i´m wrong.
The new VG´s (VG202?), replacing the ATA, will support T.38.

regards,
Gregor
