Betreff: [OSL | CCIE_Voice] Weird Error on 7961 IP Phone - DNS Unknown Host All - I am working on Workbook 1 Lab 2, going through some very basic registration tasks that I'm sure we've all done thousands of times. However, I'm running into an error on a phone that is confusing. Basically, one of my phones that is registered to CUCM will seem to lose its connection with CUCM and have to reregister. It occurs ever 10-15 seconds in a loop. So I connected to the phone's web page to grab some logs and this is what I see under status messages: 8:23:10a DNS Unknown Host 8:23:10a DNS Unknown Host 8:23:50a File Not Found : CTLFile.tlv 8:23:50a No CTL installed 8:23:50a SEP002155548AF6.cnf.xml 8:23:52a DNS Unknown Host 8:23:52a DNS Unknown Host 8:23:55a SEP002155548AF6.cnf.xml 8:23:58a DNS Unknown Host 8:23:58a DNS Unknown Host I also see this under debug display: 8:22:10a 10: Name=SEP002155548AF6 Load= SCCP41.8-4-1S Last=TCP-timeout 8:22:19a 23: Name=SEP002155548AF6 Load= SCCP41.8-4-1S Last=Reset-Restart 8:23:00a 10: Name=SEP002155548AF6 Load= SCCP41.8-4-1S Last=TCP-timeout 8:23:06a 23: Name=SEP002155548AF6 Load= SCCP41.8-4-1S Last=Reset-Restart 8:23:48a 10: Name=SEP002155548AF6 Load= SCCP41.8-4-1S Last=TCP-timeout 8:23:53a 23: Name=SEP002155548AF6 Load= SCCP41.8-4-1S Last=Reset-Restart 8:24:34a 10: Name=SEP002155548AF6 Load= SCCP41.8-4-1S Last=TCP-timeout 8:24:40a 23: Name=SEP002155548AF6 Load= SCCP41.8-4-1S Last=Reset-Restart Two things: 1. I am not using DNS at all. The DHCP pool is configured with a DNS server, but all the interaction between the phone and CUCM is done based off IP address. Yes, the CUCM server is not setup with a DNS name, but an IP address. 2. TCP timeout? None of my other hardware phones on my end are doing that. I'd think if there were a network latency issue on my end, my other phones would be doing this too. Has anyone seen this before? Digital Footprint: Skype: ciscovoiceguru
