[gentoo-user] asterisk 11.25 Channel 'IAX2' unable to transfer

Any asterisk guru on a mailing list?

When I was using asterisk 11.25 that was registered with astersk-1.8.28.2
My iax2 "pear to pear" call were going through.
After I upgraded both to ver.11.25 I can not make iax call between the servers.

iax2 show registry 
Host                  dnsmgr  Username    Perceived             Refresh  State
192.168.142.1:4569    N       home_serve  192.168.142.7:4569         60  Registered

1 IAX2 registrations.

Does it have something to do with iax.conf
;transfer=no		; Disable IAX native transfer

I've tried "transfer=yes" but still can not make calls between two asterisk over iax2

My dial line:
exten => 4,1,Dial(IAX2/home_server:xxxxxx@${clinic_server}/${EXTEN},30,rw)
