I guess I'm missing how this is an Asterisk problem.  You've configured Asterisk with ICE support, but disabled it in the Snom.  From the [Snom settings description of user_ice|http://wiki.snom.com/Settings/user_ice]:

Choose whether or not you want to use ICE (Interactive Connectivity Establishment). ICE optimizes the media path. This would be the case, for example, when two phones in the same network are calling each other via a long media path through other, external networks. With ICE, the short media path in the same network would be chosen, which will presumably have better quality than the long one. Sometimes this feature will stop you from being able to make calls. When this occurs, switch it off.

Configuring a setting in Asterisk that the physical device isn't configured to support is always going to be a bad idea.
