Hi,
also you should check, what your ITSP really supports.
I don't think our Cisco PGW's here at Telefonica Germany supports
properly Call-Transfer and it is absolutely ok, since we are providing
Class 4 services and not Class 5 services (which would be handled by
our Class 5 infrastructure).
Call-Transfer ist a typical Class 5 feature which is normally
supported by a PBX and not natively by a class 4 infrastructure.
Kind regards,
Carsten

Hi,
Have following issue:
Alice calling Bob.
Bob make call transfer to Charlie (works fine)
Charlie transfer Alice to David. (the call break)
Why is not possible to transfer the call more than one time?
Is it any parameters?
My ITSP use SER together with Cisco MGW.
Niklas, nothing in SIP protocol neither in SER/Kamailio makes your
scenario to fail. It must be a problem in your custom setup. Try
identifying the problem capturing SIP traces.
Also take into account that a proxy doesn't participate at all in the
process of a "call transfer". It's just a transparent mechanism for a
proxy.
