I would argue we should introduce a new "global title" IE which contains * BCD digits * nature of address / type of number * numbering plan indicator This would basically correspond to a SCCP global title, see osmo_sccp_gt in sccp_sap.h This is the most flexible way to encode any MSISDN, IMSI, ... just my thoughts... -- - Harald Welte <[email protected]> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
