The interworking of ISDN User-to-User IE to SIP INFO is
applicable only to the Euro ISDN, QSIG, and 4ESS PRI
variants.
To interwork the UUIE header from SIP-to-ISDN messages
with the 4ESS ISDN variant, the parameter

[EarlyAnswerTimeout]
Defines the time (in seconds) that the device waits for an ISDN
Connect message from the called party (Tel side) after sending

disabled).
