I have calls coming into my cluster in E164 format, whilst retaining 7 digit internal extension numbers. I have two clusters setup using a non-Gatekeeper controlled inter cluster trunk, the issue I have is the + not being sent across the ICT, for example:
Looking at the logs on the 4006000 cluster the + does not appear, so assume its not supported across the ICT, so my question is how can I re-insert the +, I have tried to do this using the Incoming Calling Party transformation on the Trunk however I can't get this working to update the originally calling party number (44141123456), I can only seem to modify the calling party initiating the call across the ICT (5006000)
What versions of CUCM are you using?
SIP is Cisco's recommaded integration method on recent versions, is that not an option for you?
i think the h323/ict removing the + of the redirected call
as Chris sugested can you try SIP instead !
no sure in call manager if you can add the + to the redirected number you might need a CUBE in between with translation pattern to prepend the + to the redirected number
again this is just assumption its better to test
This is a limitation of H323 which is what is used for ICTs. You have to use SIP or add the + back via calling/called party transformations.
i would suggest to use sip trunk where we can use incomng transformation CSS to insert + sign on ANI.
