Hi,
Thank for the quick response.
The issue occur only when the Alice is a PSTN client.
My ITSP says that they only supporting one call transfer (very strange).
They can not explain why etc...
PSTN client: Alice
MGW/MGC(ITSP): Cisco/SER
Our sip server: SIPX

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.
