We have been deploying ATA 186s using port forwarding.
Am I correct in understanding that you have been deploying with NAT but without the need for port forwarding.
Could you please describe the required settings on the ATA
Thanks, Dinesh

Hi,
We have deployed many Cisco ATAs behind NAT devices. In order to keep the NAT session binding alive, we enabled a feature on the ATAs that basically send a small dummy packet to SER every 90 seconds. Everything works great. The question is, how can I suppress the WARNING/ERRORS that these dummy packets present to the SYSLOG? Is there a simple way to do this in the ser.cfg file?
These are the SYSLOG messages:
May 1 09:20:58 maui /usr/sbin/ser[23389]: WARNING: upstream bug - 0-terminated packet May 1 09:20:58 maui /usr/sbin/ser[23389]: ERROR: parse_first_line: message too short: 3 May 1 09:20:58 maui /usr/sbin/ser[23389]: ERROR:parse_first_line: bad message May 1 09:20:58 maui /usr/sbin/ser[23389]: ERROR: parse_msg: message=<> May 1 09:20:58 maui /usr/sbin/ser[23389]: ERROR: receive_msg: parse_msg failed
Thanks, Ricardo
It all depends on how the NAT device handles the ports. If the NAT device changes the source port (5060) to something else when the ATA tries to register with SER then you do need port forwarding. But if the NAT devices keeps the source port (5060) the same when it sends the packet out to SER then you do not need port forwarding. You only need to tell the ATA to send a dummy packet to SER every 90 seconds or so. The parameters are:
NatServer:<your ser server> NatTimer:0x0000005a
We have encountered both types of NAT devices in our deployment.
Regards, Ricardo
