There is a customer that they have got a Cisco AS5350 ,
Users connect to that and they will be connected to a sip server in India ,
During user is connected to the India they like if they press ** they just get disconnected from India SIP server and connected to the data center in Australia ,
I have contacted some voip tech before and they said as soon as a session is created from calling and called party , the first (source) router (AS5350 in this case) can not see DTMF signals and
So that is not possible .
I like to know if it is possible to press ** ,while connected to SIP server of India , and AS5350 automatically disconnect from India and connect to the Call centre in Australia ?
So it will be :
User -> AS5350 -> SIP server 1
After press **
User -> AS5350 -> SIP server 2
