No.  Let's look at it binary:

Phone:    1100 0000 1010 1000 1000 0001 1000 1101
PC:       1100 0000 1010 1000 0111 1111 1010 0110
Netmask:  1111 1111 1111 1111 1110 0000 0000 0000
                              ^
Those third octets being on either side of 128 means that the high-order
bits are different, so you have to mask the whole thing off.  Either that,
or you must change one or both IP addresses.  Since the phone is getting
its address from DHCP, it might be easier to change the PC's address to
192.168.129.xxx if you can't change the netmask.
