> While investigating why the SIP native T.38 test was failing post https://reviewboard.asterisk.org/r/3585, I discovered that the PJSIP native T.38 test wasn't really ... native.
> Due to using a framehook to read/write T.38 data, the {{pjsip}} channel driver will never allow {{bridge_native_rtp}} to be used.
> A few things need to be cleaned up:
> # We probably shouldn't rely on a framehook to do all reading/writing. Image is a valid media stream and should be stored in {{chan_pjsip_pvt-media}} - and read/written from {{chan_pjsip}}
> # {{chan_pjsip_get_rtp_peer}} should be updated to check the state of T.38 negotiation. If T.38 has been negotiated successfully, we need to forbid remote bridging (which was the bug in the {{chan_sip}} code). This is particularly needed as the gateway framehook will soft hangup a channel, causing a bridge reconfigure (and this function) to be called
