Hi there Mitel friends.
I am having a problem with a SIP Link Alarm.
I programmed a SIP trunk between a Mitel 3300 Cxi and a Free PBX server. On the Free PBX server I can see that the trunk is register and I can make calls both ways.
But on the Mitel I am keep getting SIP Link Alarm.
These are the messages though maintance command
There are 1 SIP link(s) programmed.
Link CCS state is IN SERVICE (link down count 1) - REGISTER Failed
Number of established links: 1
Registrar Configuration
-----------------------
Domain: 172.21.2.251 IP Address 172.21.2.251
Allow Third Party Registrations: no
Default Expiry Duration: 3600 seconds
Maximum Configurable Expiry Duration: 7200 seconds
Can someone help me how to solve this alarm issue?
Best Regards,
gimitel
