Within a layout of Asterisk as server, a soft-phone on a desktop workstation
(SJPhone), and pjsua_wince on WM5 device I am experiencing the following
symptom:

Voice spoken at the desktop end is heard well in the mobile device, but not
the vice versa. e.g., words spoken on the mobile device yields a metallic
effect in the PC Speaker.

I consulted a colleague and he said that maybe the jitter buffer is not
sufficient.

Anyone dealt with such or alike in the past?
