My MicroCell (MC) and Ooma VOIP both use ports 123 UDP and 443 TCP and since my voice is breaking up using my iPhone5 over the MC, I called D-LINK who makes my router (DIR-655) who suggests I see if I can change the 2 port numbers on either the MC or Ooma so there is no duplication of devices on any port.
Ooma can't be changed.
Can I log into the MC like you can log into a router and change the port numbers?

No. There is absolutely no user access to the MicroCell at all. It is a totally closed system and even AT&T can't change the ports. Ports 123 UDP, 443 TCP, 4500 UDP, and 500 UDP (Public and Private) are what you need if you wanted to do port forwarding. Port 123 is needed for NTP Timing and 443 is needed for HTTPS over TLS/SSL. FYI, the MicroCell is not a VOIP service like Ooma is.

Dang. Well I sure hope my voice quality problems aren't the result of the shared ports. I can always turn off 123 and 443 in my Virtual Server for Ooma and see if that improves the MC as a test. Hardwired inaccessible stuff sux.
Thanks for your input and expertise.
