IPC with Nortel CS1K using PCA's IPC with Nortel CS1K using PCA's voodoochile (TechnicalUser) (OP) 15 Sep 10 09:19 Has anyone had any problems on the IPX MAX using Nortel's PCA's. Occasionaly we miss calls on the turrets and we believe it is due to the implementation of the PCA's RE: IPC with Nortel CS1K using PCA's voodoochile (TechnicalUser) (OP) 29 Sep 10 15:51 IQMAX relatively new, and Nortel about 10 years.Current versionsdAlliance version 15.1Nortel version 5.0 RE: IPC with Nortel CS1K using PCA's Redwoodbob (TechnicalUser) 5 Oct 10 16:34 How do you miss calls? Turrets not ringing? Is it from a specific number, area code or exchange? It could be a turret setting. Do you have a DND key anywhere on the turret? If so and its red, hit the DND key to turn Do Not Disturb off. You may also want to check ringing; MENU>Ring>Ring> check the lamping and set accordingly>save>quit.How is your turret system integrated with your Nortel system? QSIG? How is dial tone delivered to your Nortel? Sip?The latest IPC version I would work with is 15.3.3, newer than that I have heard has issues.
