Hi,
I have a voip platform that has a SIP server where about 450 sipura phones &
adaptors register. On two occassions some phones (which were previously working)
have refused to register with certain IPs but when I change the IP the phones
register. The failing IP can the work after two days.
A trace from the server shows that the phone is sending a registration signal to
the server & that the server is also sending back the same but its not
getting to the phone.
What could be the cause of this?
Thanks,
Edwin

The reason could be bad routing, IPs used by multiple devices.. n so on...

Running out of ARP table space on the Linux box if not going via NAT? Gordon
