Asterisk logs will not help at all.

Did you configure buttons by hand, or you use autoconfiguration for freepbx?

If configured by hand, how does your buttons.cfg file looks like?

Did you try transferring sip to sip ? Are you positive the problem is because of DAHDI? Or just a guess?

[Magvai]

Buttons configured by hands
example below:
[SIP/575]
type=extension
extension=575
context=from-internal
label=575
mailbox=575@default
extenvoicemail=*575@from-internal

Sorry was wrong, i can't forward calls not just from DAHDI, actually i can't foward all incoming calls. If i dial any number forward works.

The most probable cause is that your dialplan does not use a context named "from-internal".

The context setting must be the dialplan context where you can reach an extension, I do not know your dialplan so I cannot say, perhaps you use the "default" context for your extensions? Whatever you use, you must use that context in the button configuration file.

Best regards,
