cisco 2651XM router
I have a couple of cisco 7920 phones, they are connected to a cisco 1242AG access point which is in turn connected to an NM-16ESW switch in a cisco 2651xm router. The problem is noise and static on both phones and happens with both internal and external (sip trunk) calls. I also have 7940 desk phones on the same router but they do not have any noise problem. What's really weird is if I squeeze the 7920 phone while it's at my ear the static and crackle increases. I tried a different voice codec in the router but it made no difference and I've always used g711ulaw. I also have 'no vad' on the dialpeer. I figured the problem may lay with the access point config but I don't know. Attached is a the access point running config, thanks if anyone can help.
