DTMF NOT WORKING VIA VCS GATEKEEPER

Problem with systems connecting to a remote CMS with a PIN assigned to the space. 

Example:   dialing 698430XXXX

Connects and asks for PIN number and #

Enter PIN from keypad and nothing happens ... 

Local systems at remote site are able to connect with no issue. 

Configuration 

CMS (SIP Trunk) to VCS Control

Remote Site has a Neighbor (H.323) Zone with the remote VCS. 

both VCS's have interworking enabled. 

 

I can connect to the CMS to a SPACE with no PIN assigned with no issue.

Sounds like you may be having an issue with the Interworking of the DTMF between SIP and H.323 (and perhaps multiple interworking steps back and forth in your call path which will always complicate things).  If you can simplify your call path so that there is as little interworking as possible, that will usually help.  One example is your neighbour zone - if that can have both SIP and H.323 enabled instead of just H.323, this can reduce one possible step in the call path where interworking may occur.
