Two things you need to check. One is the web service URL, is it corrected? another nothing is make sure the user is registered in PBX.

um....it's really hard to tell what goes wrong based on the error message you posted, what configuration you have for both PAL? Make sure to have two configuration file for each PAL, and their local port will be different. Otherwise there will be port conflict, same thing happened to me the first ...

Are there any error messages? second program just terminated like that? Can you post your config.xml here? maybe something is wrong in the configuration file.
