Hello, I have the following problem between a cisco voice gateway (H323) and a PRI from Albacom:
At random moments, one needs to try different times to connect to certain numbers.
After troubleshooting, we noticed that the PSTN sends a disconnect message right after the setup message. Because of this disconnect message, the Telephony System disconnects the call.
A support ticket has been opened at Albacom with the following reference: 1/713337221
