[Linphone-users] IOS Problems

[Robert Dixon]

1. I am using 3 Iphone 4.   Occasionally one or another will say “Network 
down”. What exactly does this mean?
It is strange because the DHCP server says the phone is connected and has an 
address.  I can change to a different wireless network and the message does not 
change.  When one of the phones has this message, the others do not.  When this 
message is displayed, the phone cannot place a call.

2.  My 3 Iphones can call fine into a Mac.  They are all on a local LAN, with 
no external server.  They call via IP address. But they cannot call one another.
This used to work fine.   I may have fouled up some setting accidentally.  Any 
suggestions as to what might be wrong?

Thanks!
