Thanks for your assistance with this. I ended up restarting the Call Manager service on that node and now the SIP trunk is showing up and stable for nearly 24 hours.

I have one Publisher and two Subscribers with a SIP trunk to a fax server (XMedius). All other SIP trunks on all nodes are stable except this XMedius fax SIP trunk. Because I was seeing this trunk dropping every so often I pulled some logs from RTMT to check the status from each node. One of the nodes, a subscriber, shows no outbound OPTIONS PING traffic. Is there a way to restart the SIP trunk OPTIONS PING operation from just the one node? The only place to make any changes to the SIP trunk in CUCM handles it for all nodes, not on a per node basis. Do I have to reset the SIP trunk from there?

Thanks for all your help on this issue. I was able to collect some traces and pulled them up in Translator X. I see good outgoing and incoming TCP messages for one of my subscribers and the publisher, but the other subscriber shows no attempts on SIP OPTIONS. That would explain why RTMT shows that node down for several days. I am going to try and capture a time when one of these other two drop service. Do you know any reason why there would be no SIP TCP chatter from the one subscriber? I have even looked into the firewall rules on each node and they appear the same, but I am not experienced with them at all. The default SIP signaling source port is 5060 for XMedius. 139 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:5060 flags:0x02/0x02 limit: up to 35/sec burst 7500 mode srcip-dstport 140 LOG tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:5060 flags:0x02/0x02 limit: avg 1/min burst 1 LOG flags 0 level 4 prefix ` Exceeded hashlimit ' 141 DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:5060 flags:0x02/0x02 142 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:5060 limit: up to 1000/sec burst 10000 mode srcip-dstport 143 LOG udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:5060 limit: avg 1/min burst 1 LOG flags 0 level 4 prefix ` Exceeded hashlimit ' 144 DROP udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:5060

The phones are all in same location for the most part. This is a fairly simple environment with about 150 devices. Only a handlful are in another smaller site. These devices showing up unregistered are not related to the smaller site, though. As for DHCP, I am really not in control of that here. I thought it was strange that the SYSLOG would show devices with a /0 subnet. The majority of the /0 devices are CSF clients that bounce between wireless and wired LAN when they dock/undock laptop. There is at least one device I have seen in the SYSLOG that is a 7841 hard phone that showed a /23 and a /0 entry which made me curious.

I have all of the nodes defined in XMedius the same and their support has looked them over. Can you explain how to look for the OPTION request/response in RTMT?

Hello, I have a SIP trunk between CUCM and Xmedius Fax server that has shown stable for over two days (Full Service in CUCM). However, the application logs in Syslog viewer show the SIP trunk alarms repeatedly coming in on one subscriber and completely OOS on the other subscriber. The Publisher has it bouncing but not as much as the first subscriber. I am unable to locate any information on the protocols from each node to report back the status of Full Service. If each node is using Options Ping to check the status, which is responsible for the status Full Service. I have Run On All Nodes checked, but I am not sure this has anything to do with it. I ran a ping from the CLI on the second subscriber that is reporting it OOS, but I ping fine. Solarwinds shows the trunk state from that subscriber is Unknown. It seems each server is getting different results.

I have seen mostly the devices show unregistered of reason code 10, 18 or 23. These indicate TCP timeout or the device closes the TCP connection due to seeing higher preference in CUCM group. This happens sometimes even when it is already registered to the highest preferred node. I am seeing strange things in SYSLOG also like a device with a /0 and another entry showing the /23 subnet which it should be. This is getting uglier the deeper I look. Now I start to wonder if I should look for something in DHCP.

I have been getting alerts in SolarWinds when the registered phones drop below 5% of the total. All of our devices are set to register to the same "main" subscriber, but I notice different devices trying to register with other servers in the cluster. When I check them in CUCM, they always show up registered to the correct subscriber. This leads me to think these devices are briefly losing connectivity and then trying to register to each of the other servers in the clusters before settling back on the correct subscriber. Is there something in RTMT that I can pull to see why this is happening? A couple of devices here and there will just show up as unregistered on another server.
