Hey everyone, Hopefully someone can point me in the right direction for this. Currently we have two offices, all using Polycom 601 Revsion E I think. All have the same configurations and firmware versions. The differences: Office A: public IP address. Office B: NAT (router has a static IP) Office A: Same state as the asterisk server (Michigan) Office B: Wisconsin Office A: T1 network to the colo where the asterisk server is located Office B: Wireless connection (2 tower hops I think) (our wireless connection, we are a small ISP) to our backbone to the colo Okay, so calls going to and from office A have no problems at all. Office B is having a bit of a delay (about 5 seconds before the CLI shows the call is even started). The odd part is, it only happens when they are making an outbound call. Incoming calls go directly to them without any problems. Both offices for external calls use our PRI we have installed and all interal are SIP. I think also internal calls are having the same problem, but that I haven't had a 100% sure answer if it is or isn't, but I know for sure the PRI calls are. My question is, does it sound like the phone is causing the problem, or the network being NAT, wireless connection, or both having more to do with the problem. While I know it isn't an answer you can say, hey this is the solution, I would like any input or experience that anyone has had with a problem like this. Thanks Kevin

First, what is the latency between Office B and your * box at the colo? What is the latency between office A and your * box? Compare these two and see if there is any corrilation to the delay when making a call from office B. If so, then its unfortunetly your network configuration (using wireless network). I know this isn't very useful, but hopefully its at least a start in some direction. Another thing which is probably veeeery unlikely (but who knows)...maybe the phones at office B are not setup with a digit map and they are having to wait for the DTMF timeout to be reached before sending the call? Silly, I know. - Gabe

I'm in NY and tried to set up video conferencing with them. We ran into HUGE delays that made it impossible. That being said, do you have another site (maybe your home) that can connect to office B just for some reference testing? Maybe you could just use an IAX softphone. I would venture a guess that it is the wireless connection and not the NAT or phone that is causing the problems. - Noah
