Transfer 2 digits extension to 4 digits extension in unity

We have upgraded from 2 digits to 4 digits extensions. When a caller calls in our main line it goes to the greeting voicemail in unity. Is there any way to program the caller input for 2 numbers so when the call can be forwarded to a subscriber when his old 2 digits extension is dialed in unity??

Every subscriber can have up to 10 alternate extensions that, if forwarded into Unity will go right to their greeting.

two digits is not supported by Unity out of the box but you can hack a registry key to force it to be allowed (TAC will not support this, however). If you go into the registry to HKLM\Software\Active Voice\Doh\1.00\

you should see a key called "Minimum Handler AVP_DTMF_ACESS_ID length" there - it's set to 3 - if you set it to 2 the SA will let you create 2 digit extensions for subscribers and call handler.

Be aware, however, that if you're using digital network with multiple servers doing this can cause addressing problems. If you're not using digital networking then this wont be a problem.
