issue integration CUCM 6.1.2 with exchange 2010

[mohamedessoufy]

Hello,

I configured a Trunk in CUCM 6.1.2 to integrate Exchange 2010 UM as voice mail.

when i call the voice mail pilote number there is a silence and after a busy ring.

in the excnahge event viewer i have a warning : "the following UM IP Gateway did not respond as expected to a SIP option request"

do you have an idea to resolve this please.

Regards,

Mohamed

Hi,

Pls verify settings below System > security >SIP trunik security Profile for your SIP trunk:

1. uncheck "Enable Application Level Authorization" to see if it works.

2. If not then pls upload detaied ccm sdi and sdl trace and corresponding event message you found on exchange.

Hi,

If issue remains after uncheck "Enable Application Level Authorization" then please open a case with TAC. We will help you from there.
