[Serusers] AS 5350 + Ser Problem

[Razvan Nemesiu]

Hi Alberto,

Thanks for your help and I will try to implement this to see if it does  
what I need.One more thing.I suspected that this situation is only  
available during call setup and that's why I asked about that timer.The  
idea is that after the first preferenced destination is chosen and the  
gateway realizes that something is wrong it tries the second preferenced  
destination but after x seconds.Is it possible to adjust this time ?

Thank you and best regards.
