Old 17xx serie routers used as voip to ISDN gateway
Multiple Vic-2bri nt/te cards configured in a single trunkgroup
Is there a way to avoid use of any telco BRI line when it is faulty (no basic layer present or no line at all) ??
Does router recognize somehow when a BRI line is KO ??
In my simple configuration, it seems sometimes calls go missed when some provider line is temporarily out of service
Thank you
