I ran into exactly this problem last week with Rogers. All traffic
from the client except udp/5060 could be received by us, and udp/5060
was blocked. We tested other IP addresses on our (provider) side and
did not find any blocking there, so we assigned a new IP to the SIP
gateway. I hardly think this can be an ordinary malfunction, but good
luck getting a phone company to troubleshoot a problem with their
subscribers using mobile data to connect to a third-party voice
gateway...
