hi. i just returned from a trip a couple hours ago. while i was away, my number was ported from telus to koodo for my new wireless home phone plan. there were no messages when i got back (i was able to access voicemail), and so i wasn't sure if it was working yet. i had my partner call, and it worked. within an hour or two, there is no longer a dial tone. i've un- and re-powered the phone and the modem, took out the sim card and put it back in, un- and re-plugged the phone on both ends of the cable. the modem is showing a signal between 3 and 5 out of 5 bars, though it appears to reset every now and then. nothing's worked to get the dial tone back and i can't make outgoing calls. not currently sure about whether incoming calls are working. what can i do?
