[cisco-voip] Cisco Pri -> BRI -> Polycom HDX 8000

[Reindl Bernhard]

Hi Tim

Many Thanks for your help

This guide was solving my problem, now it is working fine...

The problem was that the networks clock select  command and isdn tei-negotiation first-call on the BRI.

best regards

Bernhard

Hi,

Whats not working?

Have you done a debug isdn q931?

This is the guide you are after
http://www.cisco.com/en/US/tech/tk652/tk653/technologies_tech_note09186a00804794c6.shtml

On the cisco side.. hardware and clocking is the essential bit. Read the requirements and restrictions carefully.

Once your config is done according to the guide.. the last problem I saw with this.. the provider was not allowing video calls on the PRI. A debug ISDN q931 will show you a cause code for this though.

Cheers,

Tim
