Hi, On the draft-vandyke-mscml-06, I have a question on which SIP messages can carry a MSCML payload for IVR commands. Section 5.2 has the following text: The application server can include any MSCML command in the initial INVITE, with the exception of asynchronous commands, such as <play> or <record>. The application server must issue asynchronous commands separately (e.g., in INFO messages) to avoid ambiguous responses. Section 6, IVR, has the following text: One may carry the request payload for IVR in either the initial SIP INVITE or INFO requests. Based on the above, it is not clear whether an initial INVITE can carry a MSCML request for an IVR command such as <play>. For example, is the following flow valid? App Server ----INVITE (IVR service, MSCML request for <play>, SDP of caller)---> Media Server App Server <----200 OK (SDP of Media Server)---- Media Server App Server ---- ACK ----> Media Server Announcement is completed. App Server <---- INFO (MSCML Response for <play>)---- Media Server App Server ---- 200 OK ----> Media Server Thanks for your help in advance, YoungSun _______________________________________________ Sipping mailing list https://www1.ietf.org/mailman/listinfo/sipping This list is for NEW development of the application of SIP Use sip-implementors@cs.columbia.edu for questions on current sip Use sip@ietf.org for new developments of core SIP
