isdn issues

I have a GW connected to a legacy PBX with 15 channel PRI.

I can call from IP side to legacy site no problem. When I try and call from legacy to IP I get the following disconnect code

"Quality of service not available"

also when I try and call the DDI number of an ip phone, (which goes through the PBX) I get erro "user busy"

any suggestion at what to look for? is there a command that shows you which dial peer the call is using

Thanks

Re: isdn issues

debug isdn q931 shows "quality service not available"?

You need to debug each side and look at what your sending/receiving from both sides of view
