CAllManager 4.1.3 Sr1 at main site. We have a remote site with Nortel opt11. connected to main site 3825 by PRI . That same 3825 has another PRI to PSTN. Both gateways are configured as MGCP. I am trying to implement FAC for international dialing. When I add a route pattern with out FAC it works fine but when I check FAC it fails . Error I get on deb isdn q931 is " No route to the destination"
However FAC works okay for phones at main site.
Are there any limitations on Tandem switching & FAC ?
