Outbound calls ring back to attendant instead of completing-ipflex

[WIBLUESFAN]

Wanted to run this by a larger audience since both my vendors are stupefied. When making an outbound call, it does not complete, but instead rings to our main attendant. The call is getting recorded by our call recording system which only records outbound calls and not internal calls. When given specific examples, my telecom provider states they do not see these calls hitting the ipflex router whatsoever, yet it has to get as far as the tap so it can get recorded. This is an intermittent issue, not limited to specific extensions, channels on the ipflex or numbers dialed. Anyone ever seen or heard of this?? Both the phone system and the router have been power cycled. We are not even using half our channel capacity when this occurs, so I don't believe it's load related.  Just plain weird

What type of trunks are you using?

B-channel according to db programming. Is that what you're looking for?

IP Flex is an AT&T SIP product. Sounds like PRI integration instead of native SIP.

WIBluesFan,

Has your vendor looked at the setup messages to see if it hits the PRI when the problem occurs? They would need to go into command console to do this so I won't explain how to do it in the forum, but they should know how.

Thanks,

So far ATT sees it hitting the router and then the call fails. They can't say why it's ringing back to my attendant. It's still under investigation. Thanks for all the input!

WIBLUESFAN,

When I said have your vendor look at it I meant it to be your Mitel Vendor not AT&T. A certified technician should know how to get into the console and look at the ISDN setup messages when the issue occurs and see what is happening and why you are getting calls back.

By the way what version of software are you running on your system?

Thanks,

TE

Thank you!  I will ask them about it. Not sure they knew to look there. I'm on call processing version 6.0.11.118

WIBLUESFAN,

We have run into a similar issue with a Charter PRI when user call certain local numbers and they use 10-digits instead of 7-digits. The system is running 5.1 and when we upgrade it to 6.2 within the next couple of weeks we are going to test again, but most likely it is a carrier issue and not a system issue as the call is actually going out and coming right back in on the same PRI.

Thanks,

TE
