Description (partial)

When the MME copies the CLID (Calling Line ID) information from SGs into NAS, it incorrectly inserts an extra header into the value ?, thereby corrupting it.

In the Paging Request Message to the MME over SGs, the CLID information is conveyedNext. The MME puts this into a CS Service Notification message. When this happens, the MME adds 0x3C08 (2 bytes) to the front of the encoding. This means that the 0x1183 prefix about the Number Type/Plan becomes part of the BCD digits, and thus the CLID sent by the MME is 113819056147028, instead of 19056147028.
