Any ideas on where to look first to correct a reported problem of delays when using VoIP phones? End user states beginning today, there's been a 20 - 30 second delay when trying to retrieve voicemail messages, and also experiences delays when placing outgoing calls (4 digit dialing over tie line to other facilities).
I'd appreciate any guidance or understanding of why delays can occur on VoIP systems.
Is the problem being reported by one user or multiple users? Have you introduced any new network devices (routers, switches, etc.) into the network recently? Are you prioritizing voice and voice signaling packets on routers and switches? These packets must be prioritized to minimize delay caused by other traffic on the network. The following link explains delay in a voice network.
It was a single user reporting the delay problem. I reset the user's device (phone). Later, in the afternoon, I checked back and was told the delay problem was gone. Does that indicate what could of been causing this particular cause of delay?
I appreciate the link you directed me to and read through it. One of my problems is lack of experience and understanding in relation to networking. Reading Cisco documents is often like trying to decipher a foreign language, leaving me with a "deer in the headlights" look. Hopefully, I'll gain in comprehension of the Language of Cisco.
Don't feel bad. We were all there once (and still are at times). Networking takes time and experience to comprehend. Don't give up. Keep reading and putting the pieces together. This forum is a fantastic place to learn and you'll find no better help than the folks who post here.
I have experienced a couple of odd problems like this that a simple phone reset fixed. The good news is you don't have all of your usesr complaining of delay. You might check the phone load to be sure that it's the latest and that the problem is not with software. You can find the procedure for finding your current software version and for upgrading the software in the FAQ linked below. You can find the latest phone software linked below as well. You will need a CCO login to access phone software.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
