Title: MBG not accepting withheld/anonymous calls
Post by: t2k on October 25, 2016, 09:13:26 AM

Hi All,

I have an MBG with teleworkers and SIP trunks connecting through to a Mitel 5000 v6. All works fine apart from withheld calls on the SIP trunks are not connecting.

I can make a call through to a teleworker on the MBG via a SIP trunk on the MBG and the call works fine, do the exact same call with 141 in front and the call doesn't connect.

I am new to the MBG and I expect this is where the problem lies, I have set up a rule on the MBG which is - Request URI - * - Primary - Mitel 5000

Any help would be greatly appreciated.

Thanks

Mitel product support should be able to help. The first thing they'll ask for is a network trace.

If this is a UDP trunk, can you provide a pcap file to look at? Also, what version of MBG is this?

Hi Navarre,

Thanks for the reply. I'm Mitel 5000 trained but not MBG so wasn't sure if Mitel support would help, no harm in creating a support call I guess.

I have a wireshark capture from the SIP provider but not sure how to upload it! The MBG is at 9.3.0.17

You can use any file sharing service.

Hi Navarre,

Attached should be a working call then the same call with 141 infront and the call fails

Hi,

I don't think the 5000 likes the anonymous.invalid and is rejecting it.
Looking at the source IP are these Gamma SIP Trunks?

On your 5000 SIP Peer under Alternate IP/FQDN enter either the internal IP of the MBG or anonymous.invalid

What happens if you test again?

Thanks Markyb73,

Adding the MBG address sorted it, much appreciated.

Thanks
