Hi,

the attached USSD frame contains two Ericsson specific fields that are not
decoded.

It would be useful for us to decode them and use in a filter.


Below a proposal for the enhancement:

wireshark\asn1\gsm_map\MAP-DialogueInformation.asn

MAP-OpenInfo ::= SEQUENCE {
 destinationReference [0] AddressString OPTIONAL,
 originationReference [1] AddressString OPTIONAL,
 callingMsisdn        [2] AddressString OPTIONAL,
 callingVlrAddress    [3] AddressString OPTIONAL,
 ...,
 extensionContainer ExtensionContainer OPTIONAL
 -- extensionContainer must not be used in version 2
 }
