How to determine MO and MT call in SIP Networks
2011-10-11 17:59:55 GMT
I am developing a SIPB2B which acts as a session controller.
No registration mechanism is implemented in it.
It will directly receives Invite from UAC and forwards it to UAS after successful billing authentication.
Can any one help me, how could I distinguish between MO and MT calls (In pure SIP networks).
Is there any SIP header to determine the call type.
