Knowing the type of VoIP application carried by H.323

63 Views Asked by At

I know that H.323 can be used for VoIP applications such as T.38 (fax over IP). Are there any fields within the H.323 packets that indicate the type of VoIP applications carried? Something similar to the SIP messages where we can find the string "t38"?
