Hi,
I currently running CUCM 7.0 with a 3845 gateway connected to a Siemens ISDX via a QSIG and everything works fine apart from when calls are transfered from Siemens (Swicthboard) to Cisco the "calling" CLI is not transfered when the call is connected as it should do. Just wondered if anybody has any ideas?
Thanks
in advance.

Hi,
Please check this debug to see if you receive the caller ID from seimens and the ccm drop it,or seimens not giving it to call manager
debug vpm signal
debug vtsp dsp

I know this post is over a year old, but I am having a similar problem with an NEC PBX transfering PSTN call across QSIG and losing CLI. Did you ever get a resolution.
Thanks

I have managed to get to bottom of this problem and it is a limitation of the QSIG protocol that the Siemens PABX uses and would say that may be the same in your case. I contacted Siemens and asked whether they could supply a software upgrade to enable extra features such as this and they have costed at £20,000!!!!!!!!!!

No suprise these makes are failing in the market.
For that price you can do a 100 extensions CME system.
