I am having issues in registaering a 7936 IP Phone on a CCM5.0. Is 7936 supported on CCM5.0?

Hi Peter,

The 7936 is supported on CCM 5.0. What happens when it trys to boot up?

If you are trying this on a normal "voice" switchport it may not work. They don't seem to like the

access vlan

voice vlan

Just set;

switchport mode access

switchport access vlan xxx (where xxx is the voice vlan)

Let us know,

Rob

Hi Rob,

I've been able to register the 7936 phone. But when I make an external call, there's a two-way commuinication, which is ok, but when an external call comes in, I can't hear the calling party but he hears me well (one way communication). Attached is the sh run. Pls help.

Hi Peter,

Well, we are getting there :) I don't have much experience troubleshooting this type of issue. I have read about the "bind command" as shown in this doc;

Troubleshooting One Way Voice Issues

Hope this helps!

HI Rob,

The document seem to be complex as it does not give one particular solution to the "oe-way communication issue". I dont seem to get the right solution. ALl the same, I'll still try more.
