>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Channels/chan_sip/Messaging, Channels/chan_sip/TCP-TLS
>    Affects Versions: 1.8.7.2
>         Environment: Minimal CentOS 5.7, Asterisk 1.8.7.0 from repo, updated to 1.8.7.2, behind the NAT.

> INVITE is sent via UDP despite previous REGISTER via TCP and TCP being declared as primary outboud transport.
> REGISTERing to external provider via TCP - Ok.
> But outgoing INVITE to the same provider is sent via UDP, despite TCP being configured primary outgoing transport, 403 Forbidden as result.
> All combinations of "transport=tcp" or "transport=tcp,udp" in general or peer section or in both - behave the same.
> 1.8.7.0 - the same.
> 1.6.2.21 - working as expected (INVITE via TCP)
