♦ RTP Fax
We support RTP faxing with Huawei devices. As configuring you should care that the D-Link router
only needs to configure fax rtp mode while Huawei router should be configured in fax protocol t38
mode, and in Huawei router you should also configure fax rate 14400 and fax train-mode ppp, as
t38 fax in Huawei router is actually transferred in RTP mode. In addition, g729r8 and
g729-compatible don't support rtp fax.
For an example, in the following figure DLINK1750 is processing rtp faxing with Huawei1760:
