If I understood your scenario correctly, you don't have a choice but to send the REFER to the same Asterisk server as the one hosting the original call leg, because that is the only server that is aware of that call leg. Perhaps I have not adequately understood. However, if your question is about whether Kamailio can initiate transfers, it can, sort of. You can initiate REFERs and INVITE-hold-REFER-BYE bridges from route script a la: http://www.kamailio.org/docs/modules/3.0.x/modules_k/dialog.html#id2700697 http://www.kamailio.org/docs/modules/3.0.x/modules_k/dialog.html#id2700815 You can also use the management interface to stimulate Kamailio to initiate a 'bridge' of this nature from an outside script: http://www.kamailio.org/docs/modules/3.0.x/modules_k/dialog.html#id2701383 If there is anything that might serve your needs, I think it is that. -- Alex -- Alex Balashov - Principal Evariste Systems LLC 1170 Peachtree Street 12th Floor, Suite 1200 Atlanta, GA 30309 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/
