Can I Add More PSTN Gateways to Add More Than Six FXO ports?
6-12 41-001190-02 Rev. 01, Rel. 1.2
AastraLink Pro 160 Administrator Guide
Can I Add More PSTN Gateways to Add More Than Six FXO ports?
No. The FXO port limit on the AastraLink Pro is six. Aastra recommends using a
SIP trunk service provider if more than six PSTN calls are required. Generic SIP
trunk servers (such as Asterisk) may be used locally.
Can I Link Multiple AastraLink Pros Using AastraLink Trunks for
Making Toll-Free Calls?
Yes! You can link multiple AastraLink Pros using AastraLink trunks. This is a toll
bypass feature. However, an Administrator can block toll bypass using the barred
numbers on the far-end system.
If the toll-bypass feature is enabled, calls made from one remote office to another
can be made using the dial pattern 7+1+9+external number. So an office in
Chicago can dial 7+1+9+external number to call an office in Dallas and the call
acts like a local call avoiding any long distance charges.
Can I Create Custom Dial Plans on the AastraLink Pro?
No. The AastraLink Pro does not support custom dial plans.
Does My AastraLink Pro Support non-Aastra SIP Phones?
Yes! In AastraLink Pro softtware Release 1.2 and later. The AastraLink Pro allows
generic SIP phones to be used as secondary phones. Each Aastra SIP phone is
given an automatic secondary account which can be used for generic SIP devices
such as softphones, etc. However, non-Aastra phones are not permitted to be the
primary account, as they do not support the required XML features.
How Many Extensions Can the AastraLink Pro Host When SIP
Trunking is Used?
Call processing capacity is based on concentration and concurrent channels. The
AastraLink Pro 160 supports 6 FXOs with 4:1 concentration, plus an operator =
25 concurrent users. Adding SIP trunks allows this to be doubled, allowing a
potential of 50 users and 12 active calls.
