The decoded MSISDN AVP in 3GPP diameter AVP and the decoded MSISDN IE in 3GPP
GTPv2 IE are not correct. 

These elements "Extension", "Nature of number" and "Number plan" are not
necessary in neither 3GPP diameter AVP nor 3GPP GTPv2 IE.

Because both two are consists of ISDN number defined in the ITU-T E.164.

ITU-T E.164 (02/2005)
    6 International E.164-number structure
It says that each structure starts with Country Code.

See also.
3GPP TS 29.329 V9.0.0 (2009-12)
"Sh Interface based on the Diameter protocol;"
    6.3.2    MSISDN AVP

It refers to ITU-T E.164.

3GPP TS 29.274 V9.1.0 (2009-12)
"Tunnelling Protocol for Control plane (GTPv2-C)"
    8.11    MSISDN
It refers 3GPP TS23.003.

3GPP TS 23.003 V9.1.0 (2009-12)
"Numbering, addressing and identification"
    3.3    Structure of MS international PSTN/ISDN number (MSISDN)
It refers to ITU-T E.164.

So, I have made two patches for each dissector file.
I'm not sure that dissect_gsm_map_msisdn should be modified or not at this
moment, so I leave it.
