Cant get incoming to work in broadvoice trunk

Ive had broad voice for years and have been using PIAF. Broad voice incomin works perfect in pbx 2.6. Id like to upgrade to 2.8 but i cant get incoming to work using exact same settings that work in 2.6. Any idea what could be the problem?

these are the iincoming setting im using in 2.6 that work fine:
username=my #
user=phone
type=peer
secret=My secret
qualify=yes
nat=no
insecure=very
host=sip.broadvoice.com
fromuser=My#
fromdomain=sip.broadvoice.com
dtmfmode=inband
dtmf=inband
disallow=all
context=from-pstn
canreinvite=no
allow=ulaw

these exat settings do not work for me i 2.8
same ports a fowarded in fw. outgoing works fine. Just incoming doesnt work
