I must be missing something.

Virtual port, ext 174, set fixed CF setting in FL51 to bin 9050. Programmed the bin with phone number

You can call 174 internally and it does the off net forward.
You dial the bin 9050 and it calls the number

But if I call in dial 174 or have them transfer me it recalls to them immediately.

Disa CO-CO for all PRI trunks are enabled. Not sure what I'm missing

any help is appreciated.
