I have 2 sites A and B, in site A i have S8300/G450 and Site B i have S8300/G450 LSP. On site B i have tieline with a nortel pbx via E1. I dont avaya extensions in Site B, just pure nortel extensions.
Now my boss wants me to check if is it possible to call those nortel extensions if my WAN fail link from site A to B by dialing the same extension numbers. Its like no matter what, i can call those nortel extension by dialing its extension numbers only. There is no ISDN terminated on the S8300/G450 LSP in site B. Only Nortel has.
I saw this feature when i do "disp dial para":
Retry ARS/AAR Analysis If All-Location Entry Inaccessible? n
Let say if ext to ext calling cannot be performed, the pbx will look for alternate path to reach those nortel extension via ARS.
I'm also looking for IGAR but dont know where to start.
