[Asterisk-Users] Snom firmwares suck <--additional datapoint to consider

[Jerry Jones]

I would like to suggest using any managed switch and hard setting the  
ports to 100/full

I have found that the auto negotiation algorithm is generally to  
blame on many switches.

As an example, connecting a cisco router to a netgear/dlink/3com/etc  
will geneerate errors on the cisco interface. connecting cisco to  
cisco does not. connectig netgear/dlink etc does not.

But disabling auto makes all play nice together.
