Mitel 5330/5340

[dbcit]

Hi All,

We have some Mitel 5330/5340 units we're trying to use with 3CX. We have noticed that after a phone or 3CX reboot, the sip extension is not re-initiated. We have tested with various timeous, however have been unsuccessful. Within the timeout period, we see the following:
Entry Method UserId URL Expires(Sec) SIPcode Status
1 REGISTER 000 sip:dbcit.3cx.com.au 60 0 Completed
2 SUBSCRIBE 000 sip:dbcit.3cx.com.au 60 0 Completed
3 SUBSCRIBE 000 sip:[email protected] 60 0 Completed
4 SUBSCRIBE 000 sip:[email protected] 60 0 Completed
5 SUBSCRIBE 000 sip:[email protected] 60 0 Completed
6 SUBSCRIBE 000 sip:[email protected] 60 0 Completed

However after the timeout (60 seconds in this case) we see the following, and no incoming/outgoing calls can be initiated.
Entry Method UserId URL Expires(Sec) SIPcode Status
1 REGISTER 000 sip:dbcit.3cx.com.au 60 0 Preparing
2 SUBSCRIBE 000 sip:dbcit.3cx.com.au 60 0 Preparing
3 SUBSCRIBE 000 sip:[email protected] 60 0 Preparing
4 SUBSCRIBE 000 sip:[email protected] 60 0 Preparing
5 SUBSCRIBE 000 sip:[email protected] 60 0 Preparing
6 SUBSCRIBE 000 sip:[email protected] 60 0 Preparing

Any ideas?
