[Asterisk-Users] SIP Registration from Verizon DSL

[Michael Welter]

I have a client who is unable to register her SJPhone on my Asterisk 
server.  She is using a Westell DSL router connected to Verizon.  Others 
in her group, using cable modems, are able to register.  The group is 
located in the Dallas area.

Is Verizon still blocking SIP registrations?

Is there something about the Westell that needs to be changed?  From 
what the client says, outbound traffic is unlimited.  In sip.conf, I 
have nat=yes and qualify=yes.

Thanks
