Hello Petr,
I have searched for some command that disallows users with a preconfigured static IP address to log on, but could not find any...
A workaround may be to configure the ppp clients to get their IP address from a DHCP server:
peer default ip address dhcp
I have not tested this, so I do not know what happens when a client with a static address connects..
Check this document for the configuration of this workaround:

c3745(config-if)#ppp ipcp address ?
accept <= Accept any non zero IP address from our peer
request <= Request any address from our peer
required <= Disconnect peers with no IP address negotiated
unique <= Disconnect if peer IP address already in use
use the "required" option.
Thanks, Mak
