I am just starting to deploy asterisk in our office to use as our primary phone system - we plan to use a Voicetronix OpenLine4 card as our PSTN gateway - but one thing at a time... haven't got that far yet. Currently, i'm trying simple IP to IP calls within the office using our Cisco 7960's phones running SIP. When I make a call between these two phones, the conversation is of a quality so bad that it is barely audible (5% makes sense). I recall having this same problem when I tested asterisk briefly one year ago. However, I did also try on this occasion to make a call between the cisco phone and MSN - that worked fine. So it would seem that the cisco phone is to blame? - but why? Does anyone know why two phones of the same type should have so much problem talking to each other? Thanks! Terence.
what firmware are you using? is it SIP? to check, push settings then status and firmware you should have a load ID like this 'POS3-04-4-00' also check the preferred CODEC we use g711ulaw as the default Terence Parker wrote:> I am just starting to deploy asterisk in our office to use as our primary > phone system - we plan to use a Voicetronix OpenLine4 card as our PSTN > gateway - but one thing at a time... haven't got that far yet.

(For what it's worth, I'm using the "ulaw" codec.) Jared Smith

What I'm trying to get at here is, it is a problem between the phones, or are you having a problem possibly with the asterisk box? Some other things to know: are you running voicemail yet? If so and you can dial into it from either of the phones, how does it sound? If not, how about anything from the * box....like the demo annoucment stuff? Daryl
Greetings...things got way better for us when we: 0. Opted for voip gateways 1. Eliminated all hubs for switches 2. Eliminated all viruses (I hate PCs) 3. Recabled and seperated our voice from our data network Three months later we just can't be happier!
