I setup some SIP extensions on my asterisk server and they work great at
home on my wifi and work great on my data plan on Verizon using my android
phone. Although at work my android phone with zoiper will not register via
wifi, but a laptop setup with zoiper on the same wifi resisters just fine.
I know my Android settings in zoiper are good because at work I can shut
off the wifi and switch to 4glte and it's fine.
It doesn't make and sense.
Any ideas?
