Controller t1 0/0/1 stays down even if PRI comes up

In one of my 2911's I have a VWIC3-4MFT-T1/E1 that terminates two pri circuit. s0/0/0:23 and s0/0/1:23 are in a trunk group. I've noticed that if the PRI flaps/bounces and comes back up, controller 0/0/1 and serial 0/0/1 stay down. Controller 0/0/0 and serial 0/0/0 always come back up. I have to restart the gateway everytime for 0/0/1 to come up. Thoughts? Interface config is below.
interface Serial0/0/1:23 description ***PRI*** no ip address encapsulation hdlc isdn switch-type primary-ni isdn incoming-voice voice isdn map address . plan unknown type unknown isdn supp-service name calling isdn outgoing ie facility no isdn outgoing display-ie trunk-group PRI-01 no cdp enable end
H.323. 0/0/0 and 0/0/1 are in trunk group pri-01 but 0/0/1 is the only one that is affected. 0/0/0 always comes back up after the pri bounces.
Both are down. s0/0/1:23 shows down down and contr t1 shows loss of signal.
That was the first thing I did, port is fine. This only happens when it loses connectivity to the pri.
edit: meant to say trunk, not group lol
ok, so i just checked what a trunk group was in this case... it appears your just logically grouping your controllers. If you have to reboot your router for this to start working again, then i have a feeling you have a physical fault somewhere. if 2 controllers are grouped together and the trunk flaps, as a result of a controller going down, then the problem is just that.. the controller that remained down until a hardware reset is faulty.
but hey.. its just my quick thought for ya.
Logically manage multiple physical interfaces as one. If you had to have 10 dial-peers for each of your 8 pri's, you'd have to configure 80 dial peers. With a trunk group, you can apply those 10 dial-peers to all 8 pri's at the same time.
Not yet, the pri hasnt bounced so the controller is still up.
This is how it is configured:
two pri circuits multilinked ----> (int 1 and 2) adtran 908e (int 3 and 4) ----> (int s0/0/0 and s0/0/1) cisco 2901
Below is the voice relevant commands of my config. Am I missing something?
