I've a big problem with SIP forwarding back into 'ringing groups'
creating what can only be described as call storms :-(
I have a 'ringing groups' of SIP phones with an effective dialplan (much
simplified) like so:
; Purchase ledger
[ptsn_inbound]
exten => _846061,1,Dial(Local/[EMAIL PROTECTED])
....
[groups]
exten => 6061,1,Macro(QUEUEING_GROUP_WITH_NS,${EXTEN},Purchase)
....
[macro-QUEUEING_GROUP_WITH_NS]
...
exten => s,n,Dial(Sip/110&Sip/111&Sip/112&Sip/113&Sip/114)
...
If Sip/110 sets their SIP phone (SNOM 300 FWIW) to call forward to 6061
then all seems fine and calls to 110 end up in the group.
If Sip/113 *also* sets their SIP phone to call forward to 6061 then
Asterisk seems to get into a state where the calls bounce around,
ringing the phones but seemingly not allowing the call to be answered.
A 'restart now' is the only way out while this call storm is in
progress.
I'm guessing that having two SIP phones redirecting back into the
ringing group is what's causing the problem but can't think of a way
around it.
Can anyone suggest a cure?
