Can the UC320 do failover for incoming & outgoing calls from FXO or FXS to SIP if FXO/FXS lines go down and also vice-versa (if SIP goes down failover to FXO/FXS)? If so is this automatic or is there a manual process? Thanks. ... View more

On the Cisco SPA5xxx phones (ie: SPA509g)..... When an extension on a BLF dials a number, and the remote phone rings, the BLF for that extension flashes red. For example, extension 100 dials (111) 222-3333. Phone rings at (111) 222-3333. BLF light for extension 100 on extension 101 flashes red. I want the BLF to flash when someone dials extension 100, but NOT when extension 100 is dialing someone. Is there a way to do this? I have looked at the Line Key LED Pattern settings under Regional, especially the "Local Ringing LED" and "Remote Ringing LED" and made changes there, but that only seems to affect what happens when an extension is rung, not when it is dialing out. Any ideas? Thanks. ... View more

When all of my Cisco 509g phones boot, they generate a syslog error message (see below) that says SCCPTCP:ERR:Can't bind to c0a801d0:5060 errno=49. Local0.Info <IP Address> SCCPTCP:ERR:Can't bind to c0a801d0:5060 errno=49 The immediate message after that one is shown below: 02-06-2011 13:17:29 Local0.Info <IP Address> [0]Reg Addr Change(0) 0:0->c0a80164:5060 Note: The numbers in italics change for each phone. I am not sure what these numbers refer to. Everything works OK, but I am concerned about the error messages. ... View more

When our Cisco SPA509g and 525g2 phones reboot, some of them come backup with the BLF lights Orange. Normally the BLF lights are green to show that the extension is idle and registered with the phone. Instead, the lights are orange. The phone's own extension is green. Has anyone seen this before? ... View more

I just wanted to let everyone know of a solution to an smtp routing issues I was having today.... With Cisco ASA and esmtp inspection enabled with an Exchange 2003 server behind the ASA, I was having problems sending & receiving emails. I am running 8.3.2 on an ASA 5510, however this should apply to the 7.x ios and other ASA models as well. It should also apply to all versions of Microsoft Exchange, 2003, 2007 & 2010. Incoming emails were either being delayed or not be received. Outgoing emails were either being delayed or not being sent. The Exchange SMTP logs were showing : For Incoming emails: dsn=4.0.0, stat=Deferred: 451 Timeout waiting for client input For outgoing emails: 421+4.4.2+mtain-dl02.r1000. <domain name here> +Error:+timeout+exceeded In addition, a number of incoming emails were being received with the body stripped out, and replaced simply with: <<< No Message Collected >>> Very troubling.... Solution: Solution is to do a 'no inspect esmtp' on the global_policy_map. The esmtp inspection is the replacement for the notorious fixup on PIX devices. Hoping this helps someone else... Here's the code: CiscoASA(config)# policy-map global_policy CiscoASA(config-pmap)# class inspection_default CiscoASA(config-pmap-c)# no inspect esmtp CiscoASA(config-pmap-c)# exit CiscoASA(config-pmap)# exit ...

Sometimes when a user goes to answer a call on their headset, the call answers on their speakerphone instead. For example if a call if on hold on a line, and then lift the handset and press the line button to answer the call, the caller is heard on the speakerphone and the speaker light is green. If they then press the speaker button to connect the handset, the call is dropped. Any ideas? ... View more
