2901 Router FXO problems

Denis Morin
Level 1
Level 1

I have a 2901 router setup as an h323 gateway for 4 fxo lines.  The problem is only 1 call can be placed at a time (inbound or outbound).  the second call seems to rings the other end once and but will not let you answer.  What would cause a router to only allow 1 call at a time?
