Hi, >Could you please clarify that , >Can I give an offer in 200 OK for a PRACK and
>>No. You can only include an answer in the 200 OK answer, if the PRACK request contained an offer. But in the normal non-early media scenario( Call initiated using INVITE with no SDP), UAS sends an offer in the 200 OK of the INVITE and receives an answer in the ACK for the INVITE. If offer can be sent in the 200 OK for scenario as described above. Then why can't the offer be sent in the 200 OK for a PRACK ? >Expect the answer in the ACK for the invite . >>The only answer you can get in ACK is for the first offer sent in a reliable (18x or 200) response to the INVITE >>(which in this case must not have contained an offer).
