The adaptation of the ring signals for the market is made from the configuration file. The
tables below shows values to be set for Europe / Standard and for North America appli-
cation systems.

11.21 CONFIGURING PRESENCE SERVICES
These telephones have menu support for activating of absence reasons (message
diversion) under the Diversion key. The menus are pushed out from the PBX at phone
logon time, and no settings are required in the configuration file for the telephone.
When message diversion is active, the lamp at the Diversion key is lit.
Note: It is necessary to set the time and date format in MX-ONE for the different
absence reasons. Use command:
extension_text with parameter ics-time-format
Common answering position(s) must be set as well so the system has a desti-
nation number where to redirect traffic when absence reason is active. Use the
command:
diversion_common with parameters
11.22 USING DNS SRV RESOURCE RECORDS
DNS SRV shall not be used in combination with ‘sip backup proxy’ or ‘sip backup regis-
trar’. DNS SRV contains a list of accesses, which may be MX-ONE servers or Session
Border Controller (SBC). As such DNS SRV is used as alternatives for redundancy. It
may be constructed as a priority list, where each priority level may have multiple
accesses tagged with a weight.
DNS SRV records can be defined in the DNS server or in the aastra.cfg/startup.cfg file.
The phone performs an SRV lookup when the corresponding port is set to 0.
For full support using DNS SRV, MX-ONE Service Node shall be addressed using its
IP address or its official DNS host name, lim<X>.<mxone-domain>, where X is the lim
number and the domain used by the MX-ONE DNS server. The ‘sip transport protocol’
has to match the DNS query protocol in ‘sip dns srvX name’. If TLS shall be used, DNS
