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.
