problems incoming calls from sip trunk to sip internal cme phones

the registration seems to work properly and also all outgoing calls work the problem is with incoming calls from sip trunk. this is the config

voice service voip

no ip address trusted authenticate

allow-connections h323 to h323

allow-connections h323 to sip

allow-connections sip to h323

allow-connections sip to sip

fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback none

h323

sip

  bind control source-interface GigabitEthernet0/1.208

  bind media source-interface GigabitEthernet0/1.208

  registrar server

using this configuration sip to sip calls doesnt work i get a fast busy signals on internal calls. but incoming calls work

at the moment i remove the lines

  bind control source-interface GigabitEthernet0/1.208

  bind media source-interface GigabitEthernet0/1.208

the internal sip phones register but incoming calls wont work

im a bit confused

do you have an ip route to the sip trunk? make sure that you have!

see if the incoming digits are correct for you extensions, see if you need any translation rule.

Make sure the sip phone can reach the address of g0/1.208, and that is the soruce address used in "voice register global".
