[asterisk-ss7] chan_ss7 statistics

[Amish]

Hi,

Is there a patch for chan_ss7 1.3 to generate statistics?

On http://www.voip-info.org/wiki/index.php?page=Asterisk+ss7+channels 
that are links to some patches, but these are for version 0.9.

How do I get the following from chan_ss7 1.3?
- MSUs received/sent
- SIF/SIO Octets received/sent
- MSUs discarded
- link/linkset failure duration
- any other useful statistics

Thanks,
Amish
