Hi all, Consider the following scenarios.
1. C->S: INVITE (for speechrecog) S->C: 200 OK C->S: ACK Now the SIP session is established b/w UAC and UAS. speechrecog resource is active on the established sip session C->S: INVITE (re-INVITE for adding speechsynth resource) S->C: 200 OK Offer/Answer fail for the new resource, TTS (speechsynth). 2. C->S: INVITE (for speechrecog) S->C: 200 OK C->S: ACK Now the SIP session is established b/w UAC and UAS. speechrecog resource is active on the established sip session. C->S: INVITE (re-INVITE for adding speechsynth resource) S->C: 200 OK Offer/Answer fail for the for the existing ASR(speechrecog) resource also. 3. C->S: INVITE (for speechrecog) S->C: 200 OK C->S: ACK Now the SIP session is established b/w UAC and UAS. speechrecog resource is active C->S: INVITE (re-INVITE for adding speechsynth resource) S->C: 200 OK C->S: ACK Now both speechrecog and speechsynth are active on the sip session C->S: INVITE (re-INVITE for removing speechsynth resource) S->C: 486 BUSY HERE What should be the behaviour of UAC in the above scenarios?
