I've got a seemingly intermittent problem that is driving me nuts trying to track down.
UC560 on a PRI. Configured using CCA. Every so often, we get an incoming call who says our main line takes about 10-20 seconds to ring. I've personally tested it a few times. Cellphone and land line. No rhyme or reason that I can find. Sometimes it connects in 0-2 seconds, other times, I get the delay. Now while I can admin the UC560, my experience for engineering an environment is no where near sufficient. Our install engineer is saying it's the PRI, the PRI vendor says their line is fine its the system. Anyone ever run into this? Any help is greatly appreciated.
