-------------------------------

hello:
I checked with my customer, the RX-level was very poor. He replaced NEW RJ45-BNC connector, the calls can up to more than 110.I think it should be a connection problem, not a problem of version of libpri(I still use libpri-1.4.13). so you can close this issue. 
Thanks!

> hello:
> my customer installs asterisk for call center, using AMI to make concurrent calls for 90 calls, the system comes out the MDL error. the error sometime change from MDL(A) or (F). 
> I try the libpri-1.4.13, the  problem is same. I use sangoma A104DE or digium 4E1 card, the problem still there. I think it should not be a hardware issue. I replace with chan_ss7, the calls can over 110 without any problem. I think something in libpri still related with this bug: PRI-149
