Cisco Unified Communications

Today, I was working with a client at a remote location. Initially, we prepped a Cisco 4331 to be installed as an SRST-CME device. This particular site has a PRI and a relatively unstable WAN connection. I prepped this router in a different location as we expected no WAN connection once it was installed. As it turned out, the PRI got turned up much earlier than expected, so now we needed to get the phones registered to the router. Well, as some of you may know, you can’t configure a router for SRST-CME AND CME at the same time. Thus begins the process of removing the SRST-CME config and prepping the new config.

Today I was working with a client who was facing some MRA issues for their 8841 handsets and Jabber. I’ve found that typically the issues are around certificates, but this client’s MRA worked sporadically. I pondered this for a few moments and asked the Network Admin to check the ports on the firewall.. as it turned out, he didn’t have access as this was tightly controlled by security.
