hi, Sunil.
It seems as FreeSwitch issue.
You may use att transfer via SIP
1. hold current call
2. invite new call
3. transfer call (with REFER message)
So, you may look at SIP trace and try to find problem point or share it
here.
Also there is FreeSwitch app "att_xfer"
Hi All,
I am using kamailio and freeswitch in my setup. While all users are
registered on Kamailio, calls are routed to Freeswitch back to kamailio and
then upstream providers.
I can make user to user calls but in cases of transfer I am stuck. I am
using a Polycom IP phone to test this scenario.
