XPhone is another SIP UA soft client [Windows PC and PocketPC/CE] that works well with SER. The Beta version is free and you can download it here: http://xphone.xten.net

erik,
i checked xphone out against our ser and had problems with digest authentication. more specifically, xphone doesn't appear to allow me to give the username to be used for digest authentication. instead, it uses the phone number as the username.
could you please add authentication username as a configuration parameter to xphone.
