Nortel Networks provides a proprietary solution to support connectivity to their

 

 

 

 

 

 

 

 

 

 

 

 

 

 

proxies from phones placed behind devices (such as routers or firewalls) that use

 

 

 

 

 

 

 

NAT. Nortel uses the SIP ping request/reply between the Nortel proxy and the

 

 

 

 

 

 

 

phone in order to keep the connection through the router or firewall active. A SIP

 

 

 

 

 

 

 

Nortel NAT timer is the interval, in seconds (default is 60), that the phone sends

 

 

IP

 

 

 

 

SIP ping requests to the Nortel proxy.
