I have configured the "route" target-type, also I configure an External Routing Point (I have never configured before).
In my ERP configuration I have some questions that I could not figure out with SIPServer Deployment Guide

(Configuring access resources for the route transaction type ), so I would really apreciate if anyone could help me with that.
This is the Procedure suggested by the Documentation:
Start of procedure
1. Under a configured Switch, select the DNs folder. From the main menu, select File > New > DN to create a new DN object.
2. On the General tab of the DN’s Properties dialog box, specify the number of the configured DN as the value of the Number field. This value must correspond to the Routing Point number on the switch.

----------->>>> Thats mean that this number must be the same of the original Routing Point in the other switch(The Avaya switch that have the call)?
3. Select External Routing Point as the value of the Type field.
4. If a dialable number for that Routing Point is different from its DN name, specify the number in the Association field.

----------->>>> What does it mean?
5. Click the Access Numbers tab. Click Add and specify these access number parameters:
Origination switch.

----------->>>> I supposed that this is the Avaya switch.
Access number that must be dialed to reach this DN from the origination switch.
thanks and regards.
