Hi,
I am running my Call Manager and the IP Phones behind the NAT. I have cisco 2621XM router with 12.3.14T2 IPVoice IOS. Call Manager is configured with static NAT while IP Phones are on Dynamic NAT. H323 is used for call setup.
Randomly, the router stops doing NAT and call manager cannot establish the call. Untill i have to clear static with 'no' command and then configure it again. Below is the message i get.
*May 9 20:11:16.099: NAT[0]: H323: received pak, payload_len=0
*May 9 20:11:19.067: NAT[0]: H323: received pak, payload_len=0
*May 9 20:11:25.099: NAT[0]: H323: received pak, payload_len=0
*May 9 20:11:54.103: NAT[0]: H323: received pak, payload_len=0
Or somtimes like this,
*May 11 05:10:26.161: NAT[0]: H323: received pak, payload_len=1
*May 11 05:10:26.165: NAT: H323: [0] Garbage Octet found
*May 11 05:10:26.421: NAT[1]: H323: received pak, payload_len=0
*May 11 05:15:26.505: NAT[0]: H323: received pak, payload_len=1
*May 11 05:15:26.505: NAT: H323: [0] Garbage Octet found
*May 11 05:15:27.509: NAT[0]: H323: received pak, payload_len=1
*May 11 05:15:27.509: NAT: H323: [0] Garbage Octet found
*May 11 05:15:27.765: NAT[1]: H323: received pak, payload_len=0
Does anyone have any idea on it.
