In your draft, you describe the handover_number IE like this:

> handover_number:                    (MSC-A <-- MSC-B, Handover Request Ack)

GSUP already has a msisdn IE:

https://git.osmocom.org/libosmocore/tree/include/osmocom/gsm/gsup.h?id=ae7966d145965452a325a33ca6334b6d6fe061a6#n244
Can we use that, and simplify the handover_number to only have
extension, nature_of_nr and number_plan?

Thanks,
Oliver
