Configuring Response Status Code Handling

To configure response status code handling , under Response Status Code
Handling make these changes:
• SIT1 through SIT4 RSC
Special Information Tone (SIT). If you set the SIT1 RSC to 404, when the
user makes a call and a failure code of 404 is returned, the SIT1 tone is
played. The Reorder or Busy tone is played by default for all unsuccessful
response status code for SIT 1 RSC through SIT 4 RSC. Defaults to blank.
• Try Backup RSC—SIP response code that retries a backup server for the
current request. Defaults to blank.
• Retry Reg RSC—Interval the device waits before re-trying registration after
a failed registration. Defaults to blank.

Configuring RTP Parameters

To configure Real-time Transport Protocol (RTP), navigate to Admin Login >
advanced > Voice > SIP. Under RTP Parameters, configure these fields:
• RTP Port Min—Minimum port number for RTP transmission and reception.
<RTP Port Min> and <RTP Port Max> defines a range that contains at least
10 even number ports (twice the number of lines); for example, 100–106.
Defaults to 16384.
• RTP Port Max—Maximum port number for RTP transmission and reception.
<RTP Port Min> and <RTP Port Max> should define a range that contains at
least 10 even number ports (twice the number of lines); for example, 100–
106. Defaults to 16482.
• RTP Packet Size—Packet size in seconds. The range is from 0.01 to 0. 1 6.
Valid values must be a multiple of 0.01 seconds. Defaults to 0.030.
• Max RTP ICMP Err—Number of successive ICMP errors allowed when
transmitting RTP packets to the peer before the Cisco IP phone terminates
the call. If the value is set to 0 (the default), the Cisco IP phone ignores the
limit on ICMP errors, disabling the feature.
