REALLY slow speedtest on UC540 - affecting inbound call quality?

Hi guys,

     Gone thru and configured everything thru CCA - the latest.  I am having inbound call quality issues with the audio breaking up.  The box is directly connecting thru a switch to a public ip.  Doing a speedtest thru my ISP ( I have 100/5 connection), I am getting 38 down and 0.07 UP!?!?!  Huh?

Am I missing something on the upload speed because that is ridiculous?

Ideas?

Thanks for everyone's time.

Jason

First of all for a true comparison you have to test with the same PC directly connected to ISP cable.

Then 38 Mbps D/L seems about right. The UC500 is not meant to be an high-speed internet router, if you want that buy either an ISR G2 router, or latest generation consumer-grade router.

For the slow upload, the default configuration leaves in a lot of useless security stuff like IP inspect, firewall, access list, etc. Once you clean out everything, should be at or close to ISP promise.

REALLY slow speedtest on UC540 - affecting inbound call quality?

Hi guys,

     Just to add to the results from different speedtests, roughly 0.24 on another server.  Obviously, something is screwed on the config to throttle it that badly.  BTW, running CCA 3.2.1 and the latest firmware. 

On another note, off topic, when will we see multiple sip trunks thru the CCA?  Jeezus!  Asterisk, 3CX, and so on have had it..

Just starting to question why I picked up this box....

Thx.

Re: REALLY slow speedtest on UC540 - affecting inbound call qual

Hi Paolo,

Thanks for the response.

I know it's not designed to be a high speed router.  I kinda figured I would have to transition to a REAL router.  I was in the process of hooking it to ISR2 1941 box I picked up and turn off all the firewall bullshit.

So, that's is the plan, turn off ALL the firewall stuff and add the port access and whatnot to the 1941 for SIP calls.

Thanks for clarifying what I suspected.

You're welcome, thank you for the nice rating and good luck!

Is this an absolute true

Is this an absolute true statement that I would never get anything close to the 100Mbps down from my ISP?  If this is the case, we may have to look at another solution for internet access.  I was told by TAC engineer to remove firewall rules and that took me from 20-25Mbps to close to a consistent 40Mbps  but never thought of this as being a possibility until I ran across it.  I was going to contact Cisco to open a case on it but if this is what I am to expect then it would be a waste of time opening the case.  Thanks
