Call forwarding issue

[npcm]

Hi everyone,
We are experiencing the following issue with Avaya Ip Office 403.
I'd like to have all calls going to my extension forwarded to an external number.
I activated the call forwarding option using Phone Manager, but this is what's happening now:
if somebody dials my extension from INSIDE the office the system DOES forward the call to the external number. But if somebody calls the office main number from OUTSIDE and then enters my extension, it does NOT work and the call goes to my IP Office voice mail instead of being forwarded to my external number.
The same thing happens if I activate the call forwarding option using the phone set keys instead of the Phone Manager software.
I double checked and the option "Inhibit Off Switch Calls" under the Telephony tab is not checked (which means that external calls ARE allowed, right?)
The external number I'd like to have my calls forwarded to is a regular phone number, with the same area code as the office. I added the prefix 9 before the external number (required to make an external call) and as I said, it IS working when my extension is dialed directly from within the office.
Is there anything I'm doing wrong? Any settings I need to change? It is extremely important for us, any help will be very much appreciated.
Thanks!

are you ending the external call string with a # ?
did you check any caveats on Rel 3.xx ? The highest you can go with 403 is a 3.xxx
did you enable trunk to trunk transfer?
are all trunks in the same group and that extension has permissions to access and dial out?
Have you run monitor to watch the call progress to track the possible error?
Have you watched system status to see what the call progress is doing on the attempted forward condition?
These standard trouble shooting procedures will pinpoint the issue. Most likely a programming error. Not always...just most likely. Good Luck

Do you have a PRI or T-1? If you do thiscould be caused by your provider not liking what it sees coming to them in the outbound caller ID field. We had this exact same issue because our shortcodes looked like this:

9xxxxxxxxxx
Nsi6105552E

When an extension dialed the system forwarded the number with a valid outbound caller ID, but calls origonating from VM itself and from the outside send an invalid outbound caller ID to the provider which did not allow the call.

Post what your outbound shortcodes look like and I will see if this is the cause. Also post your providers name and I can tell you what you can have them do as well.

Thank you both for your responses.
I figured out what was the reason of the problem:
I had to go to each individual Verizon analog line (not just the main one)in the Analog Trunk tab and check "allow forwarding".
Thanks a lot
