What should be the SIP Gateway response to the SIP network for CON or ANM Received? kk_kumar 10-June-2008 09:13:43 AMComments Response received Message sent by the MGC ----------------- ------------------- 200 OK ANM, ACK After receiving a 200 OK response the MGC establishes a two-way voice path in the MG and it sends an ANM to the PSTN and an ACK to the SIP network. If the `200 OK' response arrives before the MGC has sent the ACM, a CON is sent instead of the ANM. In SIP bridging situations the MGC sends the ANM or the CON in the response body. Posted by sagitraz When an ANM or CON message is received, the call has been answered and thus '200 OK' response SHOULD be sent to the SIP network. This 200 OK SHOULD contain an answer to the media offered in the INVITE. In SIP bridging situations (when the INVITE that initiated this call contained legitimate and comprehensible encapsulated ISUP), the ISUP message is included in the body of the 200 OK response. If it has not done so already, the gateway MUST establish a bidirectional media stream at this time. Posted by kk_kumar |
