Since yesterday any Sangoma phones that reboot, do not get an IP in the correct VLAN.
We have had many of the S705 for a couple years with no issues, correct vlan IP etc has been fine.
Suddenly with no Network/PBX/Phone changes all Sangoma’s aren’t getting the IP therefore not communicating with PBX.
We went and added the MAC info to the Cisco switches to ensure Sangoma got assigned to the Voip Vlan.
What we are seeing is that the switch assigns the Sangoma’s to the correct vlan, but somehow the phone is asking dhcp for an ip address in the wrong vlan.
A few reboot etc, and nothing has changed, any ideas?
