Hi Vijay ,

Yes you can send multiple SIP INFO without receiving 200 OK for the first
Please refer section  4.4.  Order of Delivery of RFC 6086 .

But as per your requirement please cross check if this sending of multiple
INFO will create a problem due to order mismanagement . As i understand this
is some what related to IVR / IN implementation on IP side.
