Auto Call Forwarding problem.

[tinlang]

I setup my FX-200 using VOIP -> PSTN Auto Call Forwarding and it worked flawlessly the last 3 months. And now, it has a wierd problem.
- When i place a call to the VOIP, FX-200 fowards the call to the PSTN line (in this case is using PSTN to call my cell phone).
- My cell phone rings as expected.
- But when i pick up the call, i hear a busy tone and nothing else which means the call has been dropped (i guess).

I had the same problem couple days ago and it was back to normal a day after that. And now it occurs permanently.
Here is my setup.
- Sipura 2100 VOIP adapter for the stanaphone line and got connected to the FX-200. (line1)
- The PSTN got connected to the FX-200 too (line2)
- Line1 is set for auto call forwarding to the PSTN

Everything else seems to be normal since i turn off the PSTN and it worked just fine.

I read the FAQ on the sipcpe.com and it told me to set code 31 to 5 (#1# beep 31 beep 5*#) and i did that and really don't know what it means. That was the hint for
17. My FX-200 works fine but sometimes it disconnects for no reason?
Set code 31 to 5. (#1# beep 31 beep 5*#)


Is there anyone with the same problem like me.?

Thanks a lot.

After trying to play around with the device, i found out the auto call forwarding function does not work properly. It kinda on and off since it got back to work yesterday and does not work today.
Any help would be appreciate.
