Re: [Asterisk-Users] Cisco to Cisco - poor quality
Hi Terence, I can take a look at the traces if you want. Just repeat the test using g711ulaw and use Ethereal to capture the SIP messages and RTP stream of the phone that hears bad sound, and if you can, of the other phone too (the one that hears fine). Send me the captures and I will see if there is some obvious problem.

Re: [Asterisk-Users] Cisco to Cisco - poor quality
I have managed to find time to have another go at the Cisco phones - alas, I am still having problems with Cisco to Cisco calls. Just to re-cap (it's been a few days!) i'm using Cisco 7960's and have tried setting both phones to different codecs (tried default g729a, g711alaw, and g711ulaw). Also, the other observations that have been made: - Problem is one-way. One side hears me clearly ; I don't hear the other side clearly at all (5% audible only). - Calls to MSN are fine (two way conversation is crystal clear) - Calls to a Zultys Zip2 SIP phone is also perfectly clear. - All these three tested over the same network and same VPN (call between Hong Kong and USA). - Cisco to Cisco calls worked fine with Vocal. If Cisco is able to talk fine with other devices, there should not be a problem with bandwidth or my network. However, I am finding it quite bizzarre that Cisco is unable to talk to itself. The problem shouldn't be VAD or the like - even if I talk non-stop, or the other guy does, I get the same problem. I attach a copy of my Cisco phone configuration for reference.

Re: [Asterisk-Users] Cisco to Cisco - poor quality
Thanks for the reply. The switch is indeed a full duplex 10/100, and we have a relatively small network with low office traffic so that shouldn't be a major problem in my case. Also, our cisco phones did work under vocal (except vocal is overall rather naff) so that shouldn't point to a problem with the network infrastructure. We have eliminated all viruses too (didn't have any - and yes, I hate PC's also). I haven't got round to enabling tftp yet to enable telnet on my cisco phone, so can't get the settings just this minute. But I will soonish and then I can send it off for people to look at. Currently, everything is configured directly on the phone - I take it this shouldn't be a problem?

see if you can upgrade to firmware 4-3 or 4-4 another point to note, are you using a full duplex 10/100 switch? if so, you should have 'Port1 Full 100' for full duplex 100Mbit under the 'Network Statistics' If you like to email me your config settings, I will check them against our phones. telnet to the phone, and capture 'Phone> show config' Doug Terence Parker wrote: > Thanks for the replies. > > My cisco firmware is only POS3-04-2-00, though it is SIP.
