So here is my insight to the problem:

Because the first listening interface is advertising the 192.168.1 interface, 
this one is used.
If I change the order to

listen=udp:192.168.1.156:5060 advertise 192.168.1.156:5060
listen=udp:172.23.56.1:5060 advertise 192.168.1.156:5060
listen=tcp:127.0.0.1:5060 

I can use both sockets as expected. 

Ergo: Always use the primary / actual interface before the ones which only 
advertised it!
