I’m getting some peers showing as Unspecified in the CLI.
255/255 (Unspecified) D Auto (No) No A 0 Unmonitored
This is happening intermittently to numerous peers. Sometimes they are ok, sometimes they are like this. When they are ‘Unspecified’ they won’t accept calls, but can call out.
Trying to dial an extension in this state results in:
Unable to create channel of type 'SIP' (cause 20 - Subscriber absent)
The sip.conf for this is:
 type=friend host=dynamic secret=***** context=public subscribecontext=springfield call-limit=10 deny=0.0.0.0/0.0.0.0 permit=***.***.***.***/255.255.255.0
All the peers have the same options configured in sip.conf, yet most are online all the time.
I’ve tried a sip set debug ip ipaddress but it doesn’t show any errors. The handsets are Cisco SPA504G.
Any help greatly appreciated,
