I am trying to configure 2 separate customer's PRIs to function off of the 2 PRI ports of a single adtran in a multiple business environment, but having issues with all of the calls routing to the first PRI since both of them have the same SIP binding. Is it possible in the configuration to have the call roll to the second customer's PRI if the authentication fails on the first?
Authenticate to the single SIP trunk locally on the TA908e itself.
Create two voice trunks, one for each PRI.
Create two voice grouped-trunks, one for each customer, and include the respective PRI in each.
Populate each grouped-trunk with the digit patterns for that customer's numbers.
Example:
voice trunk T01 type isdn
description "Cust1-tk"
connect isdn-group 1
voice trunk T02 type isdn
description "Cust2-tk"
connect isdn-group 2
voice grouped-trunk cust1-tg
trunk T01
accept 311-555-01XX
voice grouped-trunk cust2-tg
trunk T02
accept 311-555-02XX
You may need to tweak the number patterns if your SIP carrier sends a leading 1, etc.
