hunt-dial macro

This macro helps to define an outbound hunting group for the outbound dialing. In the situation where you have multiple PSTN lines registered as multiple SIP channels (e.g. SIP/line1, SIP/line2, SIP/line3, etc...), on the same or multiple gateways, and you wants to arrange them into an ordered hunting group for outbound calling. You can use the following hunt-dial macro.

Hunt Dialout Macro using AstDB

The above macro has been helpful in giving me the basic idea to create this macro.
The alternative macro below may be of use to you if you want to use AstDB to store your dialout SIP device information, which you may edit or add dynamically without modifying your extensions.conf

This macro is brought to you by Ossteq.com, an Asterisk Contact Center and Linux BPO Service provider in Singapore. Feel free to contact us thru our website.

Store your SIP Device Info on AstDB:
Family : Key : Value
ossteq_dialout : 1 : SIP/1001
ossteq_dialout : 2 : SIP/1003
ossteq_dialout : n : SIP/XXXX
