I have an S8700 (CM1.3) with a mix of 4610s and 4620s (Not sure of the firmware version-I’m not on-site-but it should be a version that was available around the same time as CM1.3). I have 9 different locations including the main location, with each location having a G700 with an S8300 LSP. Each location has the same Cisco networking gear with only minor differences (such as which subnet it’s on, how many lan ports, etc). About 5 days ago we began experiencing a problem at one location. We are sporadically getting no dial-tone on the IP phones and having the phone just “not work” (they look like they do but you can’t make any calls on them).
In each case there is no dial-tone when you pick up the phone, but sometimes even though there is no dial tone you are able to make a call (press the buttons even though there is no sound) and it goes through and each side can hear the other. The other times you can’t use the phone at all. This is a sporadic issue. Sometimes the phones work just fine, other times they don’t. This is affecting every phone at the site, so I know it’s not just the phone.
It has been working fine for well over a year. This has just started happening in the last 5 days. Nothing of note happened 5 days ago that would give any indication that something had changed. Any help is greatly appreciated!
