Can you blind transfer the call from a different User Agent (i.e. Polycom not bria)? Are you sure the ITSp is sending the calls in via port 5080? Can you call the auto attendant from the outside and transfer a call? If you cant call the AA and transfer to an extension they are probably sending the call to port 5060 and this will always be an issue.
Since you can successfully transfer the call but just NOT with audio, it is either a re-invite or firewall issue. Does the ITSP support reinvite with SDP, if not this will also be an issue. Firewalls must support symmetrical port NAT with no SIP ALG helper turned on. Some firewalls do not have a symmetrical port NAT option but do support 1:1 NAt which gets you the same effectve solution (outbound traffic is allowed but inbound traffic needs to be specified. You also failed to mention if the BRIA user is local or remote. You never said what type of firewall you are using. To test you should consider an ITSp account with voip.ms if your ITSp is not forthcoming with answers.
