Hello, While I've not personally set this up, I did run across Smart Tip that may aid in your quest. https://supportforums.cisco.com/docs/DOC-13461 Good luck, Albert ... View more

We battled with this issue for an entire year - I feel confident in stating we exhaused all our options. We replaced the SPA8800's with ISR2901+FXO, and the DTMF issue (among others) went away. ... View more

Hi Leolaohoo. Thanks for bringing this new AP model to my attention. Am I correct in assuming it can be utilized with the 2500 series controller? Specific details of the deployment are still a bit scarce, at this point, but I am leaning towards mostly light web traffic, with occasional voice/video use. ... View more

Hmm.. I wonder if that would help in our case. Early on we also came across the mismatched Port Impedance setting; originally was set to 220+820. Switching to 600 helped a bit. After that we tweaked PSTN To SPA Gain; dropped it down to -3 (actually down to -6, but since there was no noticeable improvement, set back to -3). Eventually we swapped 6945 phones for 8945 phones. Each step was better than the last, but, as in your case, they still have Echo from time to time. Most noticeable when both parties talk at the same time, by the way. Regards, Alberto ... View more

Hi Ryan, Please let us know if you come across anything that helps. Have a client who's been experiencing the same for a couple months now. Thanks, Alberto ... View more

Thanks for the responses, David. After going back and forth with SBSC for a week and a half, I was finally informed of the following: Issue: PD devices when sharing the same line transformer with Cisco IP phones 7960 with PID= 68-0808-xx may not power-up correctly at times. The occurrence of the problem depends on the sequence in which the PD devices and the IP phones are connected to the set of 4 ports served by a line transformer. PD will not power-up when it is plugged-in to one of the ports in a 4-port set where a 7960 phone with PID=68-0808-xx  is already connected.  This should not happen if the PD is connected and powered-up before above phone is connected. (The phones have been EOL since 2001/2002.) Workaround: a.    When issue occurs, unplug the 7960 phone with PID=68-0808-xx and wait till the impacted PDs are powered up, then plug in back the phone.  b.    Use Cat3 cable when connecting Cisco 7960 with PID=68-0808-xx to the switch. ...

Hello Lance, I am (or potentially will be) in a similar situation. Except in my case, the core switch is a 3750 and the access switches are SG300 series. To further complicate matters for myself, I have talked my boss into acquiring an additional 3750, in order to stack them. Anywho, for the time being, I have a spare 3750 and a spare SG300, so if you bare with me, I will attempt to create an etherchannel between the two. I will report back shortly, Albert ... View more

Hey Dave, That is a very good idea, concerning checking the PoE budget, but all switches are utilizing under 20% of the 180W budget. Also straight patch cables are only being utilized in our environment; have swapped out for new ones as well, to no avail. Last but not least, we are running Call Manager v7.1.5... and you are correct, all activity LED's flash in unision. This is something that I had not witnessed whilst on the old C3524 switches. Additionally, when I disconnect the uplink to our distribution switch (C3750), the rapid flashing seizes. ... View more

I've never heard of what I'm about to suggest, but could it be possible some device(s) is interferring with the PoE negotiation process? Although that does not explain why it only happens to certain phones. I would think all would be affected. It's a thought, though. By the way, this idea occurred to me, after witnessing the link/act LED's blink nonstop across all ports on all switches (not the case when isolated). Hopefully, tomorrow I have some time to load Wireshark on a laptop and see if that sheds any light. Thanks again, Albert ... View more

Hello, I'm in a similar situation! The computers do plug into the phones... I am willing to leave them on a single VLAN, but my question is, to which Smart Port should I set the switch ports? Thanks in advance, Alberto ... View more
