CCM To Avaya IPO

[kwing112000]

Has anyone gotten an Avaya IP Office to connect with Cisco Call manager. We have it connected over H323 trunk and we can get it to ring but nothing else. Cisco says they see non standard messages in the H323 header. There are not many options on the IPO so i am wondering if anyone out there has ever gotten this to work.

I am in the same situation. I configured an IP office IP Trunk to connect to a cisco call manager. i do not administer the cisco router. It is possible to dial from cisco phones to IPO phones and it rings but there is no audio. even worst, if you dial from cisco to an extension forwarded to an external number it works fine. if i dial from the ipo to the ccm it works fine.

¿How do you configure the IP trunk in cisco?
on the IPO, the trunk needs the gatekeeper and the compression mode. how it is configured on the cisco?

Have you contacted Cisco about configuration requirements?
I just connected a NEC2400Ipx to a CCM and the only way that the 2 systems would properly communicate is with a PRI Qsig circuit and nothing else. Couldn't call from CCM to NEC, anthing I dialed I would receive a fast busy!
I know cisco has some documentation online on how to connect to different PBX's. Check the website its very useful.
