CRA's not working - SIP Trunks

[Ryskie]

HI Guys,

Very odd one here feels like a firewall issue but don't have a clue how I prove this to the IT company.

Mitel 250 running 6.2 running 6 5610 DECT's, 1 Analogue Line, 6 SIP Trunks

We have just added SIP trunks (Gamma) to this system

When we point a SIP DDI straight to a hunt group/extension the call will be fine, as soon as we add a CRA / STAR the call will not connect, We can see the call going to the CRA on System Monitoring > Call Activity. But it seems to get stuck in the CRA then drops the call.

Any ideas? I have never seen this before.

Ryskie,

Is the CRA Timeout set to transfer somewhere or it is set to hang-up? Do you hear the audio from the CRA Day or Night Message; put one in there if you don't have one just to test.

Thanks,

TE

Hi,

The timeout is to transfer to a hunt group (If you point the DDI straight to the hunt group it works)

Yes there is an audiotex in there, which plays, but the call never transfers to the hunt group, whether that be by timeout or selecting an option.

They need a STAR for night mode, and you can only use CRA's within the STAR.

Ryskie,

Have you looked at the SIP logs to see what the system thinks is happening with the call?

Thanks,

Does the call work if you ring it internally.
Try both the CRA and the STAR.

Very good point! this would bypass the firewall.
