Removing Diversion header on inbound SIP call into CUBE
Having issues with an inbound call from a SIP provider, where the original call is going to number at other organization which is forwarded to one of our numbers. If we call our number directly it works fine.
The only difference between the working call and problem call is in the inbound SIP INVITE message, the forwarded call from the other organization system has a Diversion header.
From my initial research, the format of the Diversion header appears to be correct.

It looks like you need to be IOS 15.4T to use a SIP profile on a inbound call. I was thinking of using one to remove the Diversion header inbound but not sure if it will work since it is malformed, Maybe the CUBE will reject call before processing the SIP profile.
I looked for bugs regarding Diversion header in 15.3(2)T3 and didn't find anything yet.
Has anyone worked on a issue like this before or has further ideas?
I have been working with the other organization and providers for a few days now to try to correct it on their end, but was also trying to get the call to be accepted on our side.
Indeed the SIP Profiles work for outgoing direction only, in additon to permit the Diversion Header will force the CUBE to pass all the unsupported headers as stated on the command reference, you may consider tha fact that the device behind the CUBE also allows inbound DIVERSION.
Do a testing on internal extension , set one of the internal extension diversion to an external number which goes through this CUBE , now call the internal number from an extension and check the diversion header in the INVITE message sent by CUCM to CUBE.
Look at the diversion header and check how CUBE respond to that INVITE. You might get your answer.
Just posting for posterity, since this is old conversations, but we ran into this, it was a problem with a 'triggered invite' (designated by that counter=1 in the diversion header). We were able to get past it by configuring EITHER of these commands under voice service voip, sip:
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
