Its almost impossible to guess at a problem without some hints from
your systems. I good start might be the CLI results from both systems
when good and bad calls are made.

Without that info, a wild ass guess is that WiSIP phone is not
properly registering with asterisk, or, the registration is timing
out, or, something like that. When the call to the WiSIP phone
fails, what does 'sip show peers' display?
