ATA 187 AND CUCM 8.5

Hi

We have installed one ATA 187 But we have one issue

When we recieve a fax(is not matter how many pages are) then the ATA it supposed to disconnect the call and then to wait for other fAX

Unfortunatelly we are recieving a busy signal after the first fax

Is any parameter that we have to change for that

Is look like the ATA doesnt understand that the call has disconnected

Re:ATA 187 AND CUCM 8.5

By default ATA 187 uses t.38 for faxing, can you change it to Pass Trough? I had a similar issue and that fixed it, I'm still not sure why that made a difference! What fax mchine are you using? Does it support G3 or SG3?

Hi

I know this sounds odd, but try replacing the cable between the fax and ATA to one which just has the single pair wired up. I used to see a lot of odd issues similar to this one with FXS VICs where the cables that came with the fax (with two pairs cabled up) behaved oddly....
