we have the problem that we can not
read GSMTAP protocal in actual
Wireshark Version (our comany use
4.4.4.).
In this version the Info will shown:
"Unknown GSMTAP version (3)" if we
open Wireshark in 4.4.4 with a GSMTAP
trace.
Given the version checking added in 14623: GSMTAP: check version field this is not surprising.
But the GSMTAP protocol is readable In
Old stable version (4.2.11)
Given that this version check appeared in Wireshark 4.4 this makes sense.
Our comany allows actual version of
wireshark usage, only! Is there an
update of GSMTAP protocol in 4.4.4 or
higher in near time possible?
There is not going to be an update to the GSMTAP protocol in the stable release. It is called stable for a reason.
There is an open issue to support v3: 20252: Early adoption of GSMTAPv3 so if someone is willing to do the work, it may appear in the next Wireshark stable release, which could be created somewhere this year.
If your company very much depends on it, why not sponsor this development?! Maybe someone is up for it?
Is your capture according to the draft GSMTAPv3 proposal? Or is it in fact according to GSMTAPv2 but incorrectly has 3 in the version field? The draft GSMTAPv3 proposal looks sufficiently different that I would not expect a capture with a "GSMTAPv2 header with 3 in the version field" to work after GSMTAPv3 is implemented.
