pbxuser911 Posted December 7, 2009 Report Share Posted December 7, 2009 Does anyone know what setting the Snom phones are looking for when powered up using POE Switch ? I'm currently using the value of= power inline delay shutdown 20 initial 300 on my cisco 3550 switch but it seems as if the phone doesn't work correctly what I'm looking for is how long after it gets power is it looking to drop the Ethernet Quote Link to comment Share on other sites More sharing options...

You shouldn't have to do any real tweaks to PoE on the switch. I've run a snom 820 on Cisco PoE gear without making any changes. Quote Link to comment Share on other sites More sharing options...
mattlandis Posted December 10, 2009 Report Share Posted December 10, 2009 I agree with jlr. We have snom 3xx on cisco/linksys poe switches and do nothing special. matt Quote Link to comment Share on other sites More sharing options...
pbxuser911 Posted December 10, 2009 Author Report Share Posted December 10, 2009 on a Cisco 3550, when i first plug it in it powers up but takes a while for the phone to actually connect/register its extension, it starts the countdown process repeating prov.prequest from 20 down to 0, and at about 9th attempt it will register only sometimes, other times it will keep power cycling with polycom phones i dont have the problem, only with all snom phones i have tried its something about when the phone drops the ethernet after receiving power Quote Link to comment Share on other sites More sharing options...

You tried using the portfast feature on the switch? Running the most current firmware on the phone? Quote Link to comment Share on other sites More sharing options...
pbxuser911 Posted December 14, 2009 Author Report Share Posted December 14, 2009 I have never been able to make a snom 360 or 320 work on any cisco switch running spanning tree, and PoE Quote Link to comment Share on other sites More sharing options...
shopcomputer Posted December 16, 2009 Report Share Posted December 16, 2009 I have never been able to make a snom 360 or 320 work on any cisco switch running spanning tree, and PoE We primarily use HP switches, however I definetly have some Cisco switches out there, and never had to change any settings. You may have an old Cisco switch, that is older than the current poe standards. Quote Link to comment Share on other sites More sharing options...
