ShoreTel Mobility Router Administration Guide 147
 RTP Bridging Off/Transcoding Off: Disable both Force RTP Bridging through the Mobility
Router and Mobility Router Transcoding to keep the ShoreTel Mobility Router transparent
during SDP negotiations. In this mode, the Mobility Router does not inspect the SDP, and
simply forwards it to the other side. Except for special cases (for example, Access calls), RTP
packets do not pass through Mobility Router. This mode is most desirable when transcoding
and media bridging are not necessary.
 The Mobility-Router preferred Codecs display in the table in the following priority list.
 G.711 μ-law
 G.711 a-law
 G.729 Annex-B

Configuring PBX Options
PBX Trunk-side and Line-side options can be configured using the Configuration > Voice > IP-PBXs
> Options tab.
Line side support provides registration of the user to the PBX and routes all the call feature requests
on the Line side IP and Port.
Trunk side support does not register the user to the PBX. Trunk side support routes all the call feature
requests on the Trunk side IP and Port.
Options include:
 Caller ID Preferences (Trunk side only) —selects either Enterprise Extension or Enterprise
Full Number as the caller ID for outgoing calls.
 SIP User ID (Line side only) —selects either Enterprise Extension or ShoreTel Mobility User
ID in the User ID field of SIP messages.
 Call Forward—configures call forwarding features, including PBX-based call forwarding and
local call forwarding.
