I've problem with setup Cisco 2811 Router to use different lines for each IP Phone.
Two ISDN BRI lines are connected and 8 numbers are available.
It's not a problem with direct call to each phone. Problem is, that every phone uses one output number.
Phone with number 45 is available form PSTN network under 749-XX-45.
Phone with number 45 should use line 749-XX-45 for outgoing calls, but it uses 749-XX-40. All phones in network do that.
What configuration points should I check to solve this problem?
