Subject: ReservedGroup Usage for IPV4-IPv6 calls
To: megaco <at> ietf.org
Would like to know if the below handling of reservedGroup&underspecified SDP are valid:
Originating Side MG1(IPV6) -- MGC (supports both IPv4/IPv6) --Terminating MG2 (IP details Not Yet known)
When there's notification for offhook msg reported from the MG 1, the next transaction which consists of AddTermination to context, Apply dialtoneSG to physical term, requset on/flashhook from phy.term and add eph. termination ctxt. Along with this, when there's a underspecified SDP to be sent in the Local SDP, it's mandatory to set the reserveredGroup flag to ON in LCO and include underspecified sessiondescriptors for IPV4 & IPV6, since the terminating side support is not known at this point.
Appreciate your inputs.
