p
tion
The devices of some vendors do not strictly follow the SIP protocol. To interoperate with such devices, you must
configure the SIP compatibility options.
Use the address in the To
header field as the
address in the From
header field
• Enable—Configure the device to use the address (IP address or DNS domain
name) in the To header field as the address in the From header field when
sending a SIP request.
• Disable—Do not use the address in the To header field as the address in the
From header field. That is, the From header field contains the source address
and the To header field contains the destination address.
By default, the SIP compatibility function is disabled.
Source of the Called
Number
Configure the source of the called number.
• Request-Line Header Field—Get the called number from the Request-Line
header field.
• To Header Field—Get the called number from the To header field.
By default, the called number is obtained from the request-line, which is the start
line in an SIP request message.
SIP Fax and Modem
Pass-through
• Carry the x-param compatibility option:
 If the device receives a re-INVITE request with the a=X-modem field, it will
reply with a 200 OK response carrying the a=X-modem field in the SDP
field.
 If the device receives a re-INVITE request with the a=X-fax field, it will reply
with a 200 OK response carrying the a=X-fax field.
 When the device initiates a fax pass-through operation, the a=X-fax field is
carried in the re-INVITE request. When the device initiates a modem
pass-through operation, the a=X-modem field is carried in the re-INVITE
request.
• Compatible with T.38 fax: the device can recognize T.38-specific description
fields, and fax parameters T38FaxTranscodingJBIG, T38FaxTranscodingMMR,
and T38FaxFillBitRemoval, which are in the SDP fields of the re-INVITE requests
and 200 OK responses, do not contain :0.
By default, the compatibility options are not carried in re-INVITE requests.
