User's Manual

If HTTP_RETRY_NUMBER is set to 0 in the Device Configuration file, the IP Deskphone
performs HTTP retries continuously until it receives a response other than HTTP 503. If the
HTTP_RETRY_NUMBER is configured as a negative value, the default number of attempts is
applied.
SIP Domain DNS Lookup feature
The DNS Lookup feature enables the IP Deskphone to discover IP addresses for a specified
