Faxing between ATA 186 and ATA 187

We have ATA 186s and ATA 187s on a network and are able to FAX in and out via the PSTN just fine.  However, we are not able to FAX between these devices reliably on the internal network.  CUCM version is 7.1.5.  Any ideas??

David,

I reckon the issue will be that the ATA186 can only support passthru.

May be you are using T38 for the ATA187

Both ATAs will need to be passthru over your VOIP.
