HI,
This patch (ngcp-sems was updated from version 1.4.3+spce2.8.0 to version
1.4.3+spce2.8.2) fixes the problem with attended transfers, the patch was
posted on Friday, 4.
only have to modify the file: ngcp_cf.sbcprofile.conf.tt2 (create customtt)
line fix_replaces_ref=no to fix_replaces_ref = yes
Thanks,
Raúl.

Asunto: [Spce-user] SBC attended transfer problem.
hello,
I have a problem with attended transfers SBC environment(Version 2.8).
Behind the SBC I have a PBX (Asterisk)
when user A calls user B and it wants to transfer call to C with unattended
transfer, it works correctly, but if I make a call from user A to user B and
B calls C to transfer the call when I press the transfer button the call
between B and C drop, the A-B call is put on hold on B and C is left with a
call in limbo.
I created a file kamailio.cfg.customtt.cfg2 to add the REFER
if (is_method ("INVITE | ACK | CANCEL | BYE | OPTIONS | PRACK | UPDATE |
REFER
I've also created ngcp.sbcprofile.conf.customtt.tt2 to allow headers
refer-to and refered-by
attach traces from SBC
