Thanks I have disabled the whitelist as a test and the sip log shows not registering and the polycom log shows unknown host. I set the Polycom up exactly like one I have on an os7400 4.82 on the 4.82 I didn't receive any warnings and a stare and compare between the 4.70 and 4.82 are the same. I guess best course of action is to upgrade the 4.70 to at least 4.82. Thanks
