[asterisk-dev] Strange functionality of hardware SIP phones on Asterisk 1.4-branch

[Volkov Alexei]

Hi!

After upgrading asterisk from 1.2-branch to 1.4-branch i have a problem 
with hardware phone Edge-Core VP3302P (Image Version: 4.0,Sep 5 
2005,10:53:25) and Planet VIP-153T (Firmware Version: 1.1.2).
After some unpredictable number of calls this hardware phones became 
only accepting calls and does not allow to make outgoing calls 
immedeatly hearing busy tones in handset. Meanwhile i do not see any SIP 
packets in a wire from such a phones when making outgong call when it 
start working in described state. Only rebooting of phone helps.

Other hardware phones in same LAN  (DLINK DPH-120S and all other 
softphones) works fine.
