Question:
Are destination devices that belong to a Destination that has “Mandatory Destination Attribute” set available as choices for calls originating from a source device that does not have “Mandatory Destination Attribute” set?
Answer:
LCR would work as expected for source devices with a Mandatory Destination Attribute, but only Destinations with the matching attribute would be part of the LCR.
For example, assume the LCR algorithm returns the following destinations for a call:
LCR1 = Provider A, Destination Attribute = none
LCR2 = Provider B, Destination Attribute = T38
LCR3 = Provider C, Destination Attribute = none
LCR4 = Provider D, Destination Attribute = T38
Now assume the same call is made from a source device with Mandatory Destination Attribute = T38.
For this call the LCR algorithm will return:
LCR1 = Provider B, Destination Attribute = T38
LCR2 = Provider D, Destination Attribute = T38
