This may be due to the fact that voice.google.com actually resolves to a
range of IP addresses. When you set up your firewall, it may not be
including all of the possible resolutions for voice.google.com...

voice.l.google.com. 300 IN A 74.125.225.36
voice.l.google.com. 300 IN A 74.125.225.46
voice.l.google.com. 300 IN A 74.125.225.33
voice.l.google.com. 300 IN A 74.125.225.32
voice.l.google.com. 300 IN A 74.125.225.41
voice.l.google.com. 300 IN A 74.125.225.38
voice.l.google.com. 300 IN A 74.125.225.35
voice.l.google.com. 300 IN A 74.125.225.39
voice.l.google.com. 300 IN A 74.125.225.40
voice.l.google.com. 300 IN A 74.125.225.34
voice.l.google.com. 300 IN A 74.125.225.37

(ie 74.125.225.32-41 and 74.125.225.46)

Since these are short TTL values (the 300 means 5 minutes) there may be a
brief period where your devices and your firewall agree, before one or both
change their mind about the IP address behind that hostname.
