Hi All,
Per our Implementation, we need to provide Interface Redundancy at MGC end, the architecture we were going to implement is MGC-Active will have 2 IP interfaces and MGC-Standby will have 2 IP interfaces.Can someone help in answering following things:
1. If an Association has been established between MGC-Active (IP1) and peer MG, and now IP1 of MGC-Active has gone down and IP-2 of MGC-Active needs to takeover without breaking the current control association how can we achieve that? <<< Per "Updated
Draft ITU-T H.Sup7 “Gateway Control Protocol: Establishment Procedures for the
H.248 MGC-MG Control Association” (Ed. 0.14)" ServiceChangeAddress field can be used by MGC to tell new IP address for remaining association. But the document has suggested the use of Service Change Address field in the "Association Establishment Phase".Another thing if MGC sends ServiceChangeMethod as "Handoff" then It would mean that MGC wants a new association but that is not the case, MGC only wants to change the address for rest of the association. >>>
2. If we use MGCIDtotry field in the ServiceChange command then MGC will send this command through IP2 (as IP1 of MGC has been down) so, how will MG got to know that this request has been sent by MGC that has been registered on IP1. Shall it recognizes the MGC via MID ?
Kindly help!
