CUCM - SIP Trunking - CUBE - VWIC E1 QSIG - TDM PBX

[armin.wagenfuehr]

Hello Community, in section CUCM and CUBE I had try to find a Dokumentation they describe the szenario in the subject, but w/o success.

Szenario: CUCM - SIP Trunking - CUBE - VWIC E1 QSIG - TDM PBX.

Szenario: CUCM - SIP Trunking - Voice GW 29xx - VWIC E1 QSIG - TDM PBX.

Are this szenario´s supported?

Does anyone have experience with it?

Best Regards Armin

Hi Arim.

There is nothing special to do to setup basic call routing between CUMC (SIP or H323) and Third Party PBX  using sig through a voice Gateway.

Basically configure E1 controller and Serial interface to meet PBX Qsig requirements.

Usually what follows could be enough.

interface Serial0/0/1:15

no ip address
encapsulation hdlc
isdn switch-type primary-qsig

isdn incoming-voice voice
no cdp enable 

Than you have to setup sip trunk on  CUCM and dialpeers on VG both to PBX(POTS) and to CUCM (VOIP).

HTH

Hello Carlo, really thanks for your effort. It seems for me that no Cube Function is needed.

It is also TLS ans SRTP possible?

The VGW and CUCM could convert all QSIG Supplemetary Services and Feature to SIP?
