We recently upgraded to 7.0PR1 on both our 3300 and our VMCD. We have experienced two show-stopping bugs.
1. Controller crashes when modifying hunt group resiliency. Twice the 3300 has crashed when we modify the "2nd element" resiliency on a hunt group pilot number. The hunt group points to 16 SIP trunks on our voicemail server. As soon as this setting is changed, the administrative interface responds very slowly, and all the phones on that controller behave strangely. They experience a delay in dialing and a delay in picking up a call. Other strange behaviours have been reported, as well. The only fix is to reboot the controller.
3. One-way audio caused by congestion of logical ports. My understanding of this phenomenon is incomplete, and is based on conversations with our vendor, who have a ticket open with Mitel. We have several DID numbers pointing to ATA SIP boxes, and are experiencing a high volume of spam faxes. This is not a problem in itself. However, it appears that many of these calls are not terminated properly, and cause the consumption of logical ports on the controller. I've been told there are about 11,000 of these ports, and when they are congested, we experience one-way audio. Does this make any kind of sense to anyone?
This brings me to a general observation: we have no visibility into Mitel bugs. The Mitel OnLine site has nothing of substance in this regard. So far this forum is my best option for troubleshooting outside of vendor channels. Does anyone else have other resources that you could point to?
Thanks!
