The modem isn’t allowing an IP address to be given to my SIP phone that is connected via ethernet cable.  I verified with the internet provider no connection issue.  Any help?

What is your modem’s model?  Where is your SIP phone connected to?


Modems typically need a router connected to them to manage more than 1 device and handle dhcp. 

You didn’t give us much to go off. 

What modem do you have it connected to? 

Is there a router? 

What SIP phone is it?
