Dear Buckweet,

Oh and a comment to the person about AVAYA's hardphones and Softphones, I don't know if you're deaf or something, but their softphone sounds horrible, I don't care at what codec, their phones aren't that impressive either, this I can say that CISCO's voice quality is far superior to AVAYA's
I have not had customers we installed AVAYA VoIP complaining, now this is from the CISCO Callmanager forum:

We just installed Call manager with about 40 7940 phones. At first the quality of sound was great. However, now there is an annoying hum of line noise when the other party is not talking. The other end does not hear this noise. The noise goes away while they are talking and instantly comes back when they stop. Thanks for any information.

We had an office that complained about that too. To fix it we modified the analog voice-ports, removing the "comfort noise".
No such problems with AVAYA's Comfort Noise

I currently have 2 PRI line for my voice over ip setup. I have 50 PHONES (7960 model). From time to time we get an echo sound as though you were speaking on bad cell phone connections. Any ideas?

My guess is that you are using a HDV instead of a dt-24+
I have run into this alot. Echo at the beginning of a conversation, but fading within the first couple of seconds, is common (and according to Cisco, working as designed). I the echo is persiting, here is what you can do to make it better. T1s are usually brought to the demark at 0db. This is too hot for an HDV. Get the circuit provider to come back out and lower the level on the smartjack to -15db. Next set the output attenuation to six (you may need to tweak this). Keep it as close to 0 as you can. Raising the output attenuation on the voice port will lesson your output level decreasing the level of echo coming back. Next, crank the echo cancellation coverage to 32. Placing calls after that, you may hear an echo just when the call is placed, but it should fade quickly as the echo canceller learns the rythm of the echo.
I mentioned in an earlier post that there are some issues with this system. This is probably the most common, and most annoying to customers. Good luck.
No such problems with AVAYA, and luckely we don't need support from Service Providers to solve problems that in their opinion is NOT their problem, which will be reflected in their responce time

Hello everybody,
After my problem of conference, I have a other problem. One per week.
So: When I call an external phone number, for example a GSM, the GSM rings but I heard anything on my IP phone:
When I take down, I heard the tonality. I enter my external phone number (GSM), the GSM rings but I don’t heard the ring on my IP Phone. I answer on the GSM, there’s no sound on the IP Phone and on the GSM.
However when I call an intern phone number, there’s any problem.
I don’t change gateway, server or pattern configuration.
Thanks for your help

Check gateway of GSM device if its on a different subnet from the phone making the call. Also check codec values for the two endpoints
I think we all know how easy it is to resolve errors that happen ones a week??!!
Now this all was, in my humble opinion about sound quality and reliability of the connections (or the ability to make a connection)
If we talk about features read this:

Hello People,
Wondered whether or not anybody out there has been working on or with a Cisco IPCC, (i.e. CallManager+ICM+IP-IVR). We, (an I&CT consultancy company), have successfully implemented an IPCC for a Call Centre customer. It has provided them with the functionality that they require and, barring one or two momentary glitches, has been fullly operational for a period of nearly 3 months. However, the reporting side of things is proving a little unreliable. When running different types of reports via the Monitor ICM tool, we seem to rarely get the same figures and often the divergance in reports is 10%+. For instance a Call Type report will show X calls handled, a Service report will show Y calls handled and a Skill Group Report will show Z calls handled. In theory all should be identical or within a tolerance of 1% to 2%. If there is anybody out there with any similar issues with the reporting aspect of Cisco's IPCC, I'd love to hear from you.
CiscoICM (Visitor) Feb 13, 2002 sys:
You may want to upgrade to ICM 4.6.2 There have been many improvements to the reporting, and there are new IPCC specific templates.
Good luck!
Now I really wold like to hear what a Call Center Manager would think about unreliable reporting, especially if it would be an outsourced Call Center that has to bill based on handled calls and service levels?
Please let me know if the information that was provided is helpfull.
