Title: Mitel <>AVAYA SIP Trunk
Post by: MitelKw on June 25, 2015, 04:37:44 AM

I am facing this problem of integrating Mitel 3300 Cxii Controller with AVAYA Ip Office Manager using SIP trunks.
Although the setup has been done with the AVAYA team and Mitel Team . The Issue is, the call can be made from AVAYA to Mitel Extn. But not the other way . Either the call gets dropped or the AVAYA trace log reports Error" 402 - Bad Extension" . Both the PBx are on different Subnets. Can anybody help on this issue? or has faced this type of error. please help.

On the IPO side try building the exact digits received in the incoming call route and assign them to the SIP line group.

Thanks for the different output. We have been able to sort out the problem. It was the SDP options in MCD 3300.
@Ralph. Thanks for the Documents.
