[asterisk-users] call drops after a few seconds

[Ishfaq Malik]

I've encountered this issue a couple of times and we managed to resolve 
it by updating the sip phone and the router it was connected to both to 
use their latest firmware.

I know it's not a definitive answer but I've never truly got down to the 
heart of the issue as with us it would affect just one out of 100 or so 
extensions.
