Dundi show peers - UNREACHABLE but I can ping it!

Hi guys!!

I’ve 3 server connected using IAX / DUNDi, it works just fine.
However, sometimes when some of our links goes down the server takes
forever to appear back as OK at DUNDi’s list and people can’t call the
other Box.

It’s happening right now:

*CLI> dundi show peers EID Host Port Model AvgTime Status 42:3c:dd:86:09:bb 192.xx.xx.244 (S) 4520 Symmetric Unavail UNREACHABLE 00:30:18:a8:d4:8d 192.xx.xx.253 (S) 4520 Symmetric Unavail OK (27 ms) 2 dundi peers [1 online, 1 offline, 0 unmonitored]

# ping 192.xx.xx.244 PING 192.xx.xx.244 (192.xx.xx.244) 56(84) bytes of data. 64 bytes from 192.xx.xx.244: icmp_req=1 ttl=62 time=33.4 ms 64 bytes from 192.xx.xx.244: icmp_req=2 ttl=62 time=32.1 ms

I’ve tried to do “module reload pbx_dundi.so”, I’ve tried to do ‘dundi flush’, I’ve restarted the service, I’ve rebooted asterisk server but nothing; I can ping but dundi say UNREACHABLE.

How can I fix that problem? Tnx a lot!!
