Making Explicit Call Transfers (ECT) With E1 ISDN and BRI

„Set the transfer_variant using the callctrl.cfg configuration file:

transfer_Variant=etsi_exp_link

for explicit link transfer. You can also choose an implicit link by setting:

transfer_Variant=etsi_imp_link

„Set the country code using the btcall.cfg configuration file, leave as default:

country_code = 0010.

Country codes are listed in:

C:\Brooktrout\Boston\bfv.api\inc\ccode.h

Your application should support the European Telecommunication Standards Institute (ETSI) recommendations for Explicit Call Transfer. Call hold should also be implemented in the application using BfvCallHold, based upon recommendations from ETSI.

For more information on BfvCallHold, refer to the Volume 2, Bfv API Reference Manual. For more information on the Brooktrout Configuration Tool, refer to the chapter on using the configuration tool in the installation and configuration guide that came with your software.
