Host Capacity Limitations
Meet-me conferencing capability is dependent on the available host CPU capacity.
The AastraLink Pro supports a total of 12 simultaneous host-routed sessions.
One session is defined as a SIP trunk call, a remote office call, a conference call
participant, a voicemail call, or an auto-attendant call.
Calls directly between local SIP phones do not use a host session and are excluded
from the 12 session limit.
Configuring an Emergency Dial Plan
Public telephone networks in countries around the world have a single emergency
telephone number (emergency services number), that allows a caller to contact
local emergency services for assistance when required. The emergency telephone
number may differ from country to country. It is typically a three-digit number so
that it can be easily remembered and dialed quickly. Some countries have a
different emergency number for each of the different emergency services, or may
have additional numbers for contacting regional / locality specific emergency
services.
You can specify the digits to dial on the IP phone for contacting emergency
services. Once you specify the emergency number(s) on the phone, you can dial
those numbers directly on the dial pad when required, and the phone
automatically dials to those emergency services without needing to enter the
PSTN (FXO) prefix digit 9.
These emergency numbers are also used when checking that an emergency call is
not in progress for the FXO priority override feature described in the Chapter 1,
the section, “Emergency Call Priority” on page 1-9.
By default, the emergency number 911 is configured for the AastraLink device.
