Hello, we have a site that has two Aspire M that are Aspire net. They both have 4 voip cards. They are connected with an MPLS from Logix. After there is one call that goes across the network either outside call or internally you can not call across network until first call clears. Does Anybody have any thoughts on this?

Thanks

Did it work in the past? Has anything been changed (pbx OR network)? Has anyone done programming recently?

Yes they recently changed a firewall which was a red flag right away. I spoke with NTAC and got the list of ports that needed to be opened and gave that to there IT guys. But they are saying everything is open on firewall. But you know how that battle goes. I also got some wireshark captures I am going to send in.

Yep..troubleshooting 101. Always check the simple stuff first.

Just to give you an update I spoke to Ntac again today. Apparently there is a bug in 7.32 where all of the voip ports will lock up except for the first one. So I will upgrade them tomorrow and let you know if this fixes the issue.

Thanks
