[CentOS] rpm mgetty (fax)

Hi,

I am new on this forum. 
I use sme-server based now on centos.
Before sme-server was based on redhat 7.3.

With the old version of sme-server, I used mgetty 1.1.33.

With centos, it is mgetty 1.1.31.
Fedora has mgetty 1.1.33
The last version is 1.1.35

 Would it be possible to include the version of mgetty (1.1.33) in centos . In fact the version that is include for the moment (1.1.31) misses some important options (faxq-helper). Could you tell me who is in charge of such change in the distribution to ask him?

Thank you
anne
