[Serusers] Grandstream Handytone 286 Problem with SER

[Beau Walker]

Hi,

I have two Grandstream HT's and a SER server running on RedHat 9.0. Both 
phone register and call each other fine, but for some reason, after a random 
amount of time, the audio stops working in one direction. It doesn't make 
any difference what the register time is or if a different codec is used, it 
still does it.

If you make calls back and forth ie call one end hand up call from the other 
end and hang up, it's fine for ages, it just seems to fail audio in one way 
after you have not made a call for a while. It won't recover from this state 
until you reboot either phone at either end.

Both phones are on a wired CAT5 100MB LAN without any NAT between them.

Any ideas ?

Thanks

BJ
