Having a problem once in a while. Calls are getting droped after about 20 minutes on the call. We are running a Dual PRI card using custom 5ESS. One PRI is to the outside and the other is QSIG to 3rd party voicemail. I thout it was only happening to one person, but I just heard it is happening to another person two, but always well into the call. Any thouts. We are running 3.0.69. When I upgraded it seemed to have fixed the 5ESS issues, but I guess not. I was thinking of getting the Telco to change the protocol on the PRI.
