I have a tenant who is having a problem with most of his inbound calls. Inbound calls go to an IVR, and the caller is able to dial a three digit extension while playing the menus. When an inbound call is answered at an extension the person answering the phone must wait up to about 3 full seconds before the caller hear his voice.
So that the callers hear them answer the phone answering the phones have developed a habit of picking up the phone and counting to three before saying anything.
The cli output on the calls looks normal. The phone rings, and it's answered.
Does anyone know what this might be or have any suggestions that I might use to chase it down?
make sure ip_nat_sip isnt
make sure ip_nat_sip isnt loaded
lsmod | grep sip
add this to modprobe.conf
install ip_nat_sip /bin/true

lsmod |grep sip turns up nothing. Also, no reference to sip in modprobe.conf. Do I still need to change it? I have about 12 customers on this server, and this is the only one reporting this problem.

if its centos 5.x you'll want those statements in modprobe.conf to keep those modules from loading.
I added them to
I added them to modprobe.conf and will reboot when I have a chance. But, I don't think those modules are loaded for some reason.
