I can’t connect phones, more precisely, phones on the 1st floor are common to each other, but there are no connections on the 2nd floor, more precisely, there are no connections from the 1st floor to 2, but from the 2nd floor to 1 there are connections, I explained it clearly? In general, please help in the photo shown. for connections between, the code was
r4
dial-peer voice 1 voip
destination-pattern 10.
session target ipv4:192.169.7.1
r5

Thanks in advance!
