Good day,
We have an OfficeServ7400 and are receiving the dreaded “No MGI Channels Available” when making calls from remote SMT-i3105’s. Remote phones connect and register with the OfficeServ. However, “no MGI channels available” is displayed when making a call to/from the remote station.
Some months ago we added a second OSA card (to handle some additional SMT-i3105’s, all local) and upgrade the OfficeServ software to v4.70. At this time “No MGI Channels Available” began on the few remote phones we have. The installer claimed the problem was due to NAT issues in our Firewall. I’ve updated our NAT’s and rules as recommend by the installer, yet the problem still persist.
I’ve wireshark’ed and see the remote phone register on UDP 6000. However, I’m not seeing any traffic in the 30000/31000 range when making a call. FYI in DM 2.1.5 VoIP RTP options are set to: MPS Service: Off No MPG to MGI: On SIP to SIP MGI: On
Here is a list of current NAT’s: 5003 TCP --> OfficeServ 5060 UDP --> OfficeServ 5090-5091 TCP --> OfficeServ 6000 TCP/UDP --> OfficeServ 6001-6002 TCP --> OfficeServSVMi 6100 TCP --> OfficeServ 8000-8001 TCP/UDP --> OfficeServ 9000 UDP --> OfficeServ 30000 – 30031 UDP --> OfficeServOSA1 30032 – 30063 UDP --> OfficeServSVMi 31000-31031 UDP --> OfficeServOSA2 35000 – 35127 --> OfficeServSVMi 40000 – 41031 --> OfficeServOSA1 41000 – 41031 --> OfficeServOSA2
I need to get this remote issue resolved for a new hire. Any help is GREATLY APPRECIATED!
