Hi, I've been very puzzled lately. I installed a phone system for a friend a few weeks ago, and they're having a problem that I can't get rid of, actually 2 problems. Before I go into the problems, let me tell you about the setup. It's a pretty small setup with only 4 handsets, all Polycom 320s, the server is a Dell SC440 with Intel E2180 CPU (dual core, 2GHz) and 512MB Ram. Internet Connection is an ADSL2, with a not so reliable ISP in australia. For incoming calls, I had a Digium TDM410P with 4xFXO modules and HWEC. Because of these problems, i replaced the Digium card with a Sangoma A200D, but it didn't make any difference to the problems. All phones are hooked up to a Netgear PoE switch.
Almost forgot to mention that this is not my first Asterisk setup, and in fact it is my 4th, and I used various SIP handsets before, and also different cards (Analog and Digital), so I'm not a total noob. Let's get to the problems... 1) Some incoming calls cannot be picked up Sometimes, incoming calls, coming through the analog card, cannot be picked up. All handsets are set to ring at the same time on incoming calls. and most of the time, calls can be answered on any of the handsets, but maybe 3 or 4 times a day, all handsets will be ringing, and you go to one handset to answer the call, you pick the handset, and it doesn't answer the call, it keeps ringing, then you go to another handset, and still can't pick up, sometimes, you can even try all 4 handsets, and no luck. but, at other times, you can't answer on the first handset, but you can on another, and it is totally random. but people are pretty pissed off for running around to answer a call. and what puzzles me is that you can sit around watching logs for hours, and it won't happen, other times, it happens 3 times in a row. any ideas? 2) Delay on outgoing calls via SIP People have been saying that when they call people, there's a delay for the call to be answered. For example, caller dials a number, callee answers the ringing phone, but caller is still listening to a ringing tone, and after a few seconds (up to 15 seconds) it sounds like the callee has just answered the call, when in fact, he had already answered a few seconds before. Problem with this is that some callees will hangup before the caller starts talking. These calls are going via pennytel, in australia, which seems to be a pretty good VOIP provider around here, and I've been using it on other setups and never had these issues. Well, sorry for the long first post, but I would really appreciate any suggestions you have.
