Good Morning, I'm having trouble

Good Morning,

I'm having troubles troubleshooting a trunk-to-trunk transfer issue. I have a toll-free number routed to trunk 7. If a call is transferred or routed (via vectoring) to trunk 10, the call is disconnected. The CORs look OK, what am I missing?

Is Trunk 10 an off net trunk? If so you must allow call forward off net.

Give this a bash

Also check to see if trunk to trunk transfers are turned on. You can find this is the system parameters features forms.

Also look to see if dial access is on for the trunk group.

OK, I've isolated it to trunk 7 (inbound). Trunk-to-Trunk transfer is set to yes in features. I can call in on trunk group 7 and transfer a call over to trunk 10 without an issue. If I create a vector that routes a call over trunk 10, the call fails. If I add a wait 2 seconds hearing ringback step, the call is successful. Which brings me to believe it’s an answer supervision issue on trunk 7.

Now, trunk 7 is inbound only, if I change it to two-way, will it cause any issues with the LEC? I need to change it to two-way as I need to setup answer supervision-out. This is all speculation, but answer supervision seems likely to be the issue.

If trunk 7 is a DID trunk it cannot be set as two way. If you are "vectoring" all the calls from 7 to 10 and wait 2 seconds hearing ringback allows it to complete could this be the solution? I would be carefull in changing things on the trunk side. You might fix one thing and "break" another.

Hope this helps
Ed
