Using Alphanumeric Chars. For The Outgoing Dial Rules

Hello,

I need to route the extensions coming from the out posts with the call id like “ta3550”. When a missed call placed on a cisco 7940 phone and we try to call back it, it trys to dial like “ta3550” which is can not be added to dial rules. IS there any way to add alphanumeric routes to the sip trunk dial rules?

Btw i am using an old version which is FreePBX 2.3.0.3
