Hello, New with C9800-40 WLCS RMI + RP redundancy...I've set up my first pair and everything is fine. I ended up using the "redun-management hostname" command as WLCS A and WLCS B are in different buildings, and if there's a failover, I didn't want s...

I recently found out that since the conversion of a site from T-1 CAS PSTN connections to SIP over a year ago, that faxing has been intermittently not working. At the trouble site, all fax machines are off of a PBX, which is T-1 CAS integrated to SBC...

Marce, Thank you- I never used that tool or knew of its existence- lots of good information. Fortunately, the two errors I received are known to me and I will address. Thank you for your input, assistance and knowledge! Mike
