[serusers] calling problem

[michael p]

hi

i have a  problem :

i have 2 same softphone , 1 can call the other and the other cannot call the 
previous.
it's the same configuration for both in the softphone.

i did test about this that can't call:  i change the softphone, i change the 
laptop, i use the user that this can call use and change with mine...

in basis ser.cfg what do the difference between 2 users ? nothing i guess

i'm using a stun to pass over nat and it works in one direction (from one 
user to the other)

it didn't work

someone has an idea

thanks

M.
