Configuring SIP compatibility
If a third-party device does not implement SIP in strict accordance with the RFC standard, you can
configure SIP compatibility for the router to interoperate with the third-party device.
With the sip-compatible t38 command configured, the router excludes :0 from the following SDP
parameters in the originated re-INVITE messages:
T38FaxTranscodingJBIG.
T38FaxTranscodingMMR.
T38FaxFillBitRemoval.
With the sip-compatible x-param command configured, the router adds SDP description
information (a=X-fax and a=X-modem) for fax pass-through and modem pass-through in the
originated re-INVITE messages.
To configure SIP compatibility:
1. Enter system view.
