Has anyone integrated a Siemens HiPath PBX via H323 to CUCM? If so, what issues did you have? I know that I can do the integration with QSig & standard PRI's, but would like to utilize the IP Trunking features if possible.
I don't remember the exact modle and version of the Siemens PBX but I remember I did a Semines-CUCM integration few years ago. I used an H.323 trunk btw PBX and CUCM.
First of all, you need to make sure if the PBX supports H.323 trunk. Each call from PBX to CUCM requires two H.323 trunks, so make sure you have enough H.323 trunks available. You need to make sure the PBX has at least one Media Processor card installed. This card will take care of codec conversion. Also make sure to select "a" as the vlue for codeset in the PBX tunk-group configuration page. CUCM only understands "a" codeset. The codeset will take care of user Name/Number transmission.
please i need your help in my case , my customer has a PBX ( simenz) and he want to make voice mail .i thing in router 2811 with NM ( CUE) , so my question does this router with CUE module will integrate with Siemens PBX .
