Can not Trunk to Trunk Transfer Between systems
« on: March 30, 2020, 01:23:18 PM »
We have 4 Mitels 250's at 4 locations.  We are working remote for the Covid-19 and we have 90% of our extensions forwarded to cell phones.

When a call come into Location A from a SIP trunk and it is transferred to and extension at Location B that is forwarded to a Cell phone out it's SIP trunks the transferring phone acts like it will transfer for a few seconds then the call comes back.  The transferring phone gets a message that the Transfer Could not be completed.

We can transfer to extensions that are forwarded within the same branch fine it is only when it comes in one branch and leaves on the other branch.  We've had a high priority case open with for 5 days and they won't call us back.  Is there any type of security restriction or setting that may be preventing trunk to trunk transfers between systems?

Please help with any ideas. 
Tom

tmulkey,

This could be just a simple issue, but without seeing the SIP logs from both systems and a date and time it occurred it would be difficult to say what your issue is.

Do calls get transferred out OK when a call comes in and goes out on the same SIP Trunks? For instance if the call comes into System A and goes out of the trunks on System A does that work?

Thanks,

TE
