Hi guys,

posting from my iPhone so apologies this is brief.

Have a client with issues of phones dropping offline overnight. It seems random which one will.
Phones are Netcomm V90.

Here's the status page I wrote output:

Asterisk channel status

Peer             User/ANR    Call ID      Seq (Tx/Rx)  Format           Hold     Last Message   
 
they're using what I'd call a non-standard router, but it seems stable and connected, calls still reach Elastix inbound.

Any thoughts / help / ideas appreciated

cheers

A few things to check:
use tcpdump/tshark from the elastix box and see if the phones are attempting a re-register when they are showing as offline.

Is anything possibly coming on the network to conflict with the pbx's IP address?

Is the PBX multi-homed? If so is it possible that several network interfaces on the pbx can be accessed from the the same LAN? If this is the case you might be having ARP problems try this as a quick test:
/bin/echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
then reboot the phone to clear its arp cache and wait..
