PABX & VOIP INTEGRATION

This message is aimed at the UK.

I would like to make contact with anyone who has connected a Siemens iSDX/Realitis PABX (DLI) to E1 blades.

In particular, DPNSS to QSIG via a converter or QSIG at both ends, or even Q931!

Does anyone know if Cisco have a functionality listing for QSIG & Q931?

Has anyone had a problem where a call cleardown initiated by the IP phone takes 7.5 seconds to release on the PABX, yet if initiated by the PABX is instantaneous?

Thanks in advance.

Nigel.

Re: PABX & VOIP INTEGRATION

Yes we do qsig, you can see this opn a router by doing a debug q931

this should show what is slow in the disconnect sequence that you describe.

Re: PABX & VOIP INTEGRATION

we currently have a realitis pabx connected to a call manager system, we are using a dpnss to qsig converter to connect the router to the pabx. we haven't had any problems like you describe

Further investigation reveals that the problem seems to have started since we upgraded Call Manager to version 3.2 (2c).
