For incoming calls, the caller cannot hear me for... (by 2 users)

I have only experienced this problem with the Polycom 501 IP phone. I can make calls just fine, and I can recieve calls fine if the caller dials my direct number. However, If a caller dials the main number here and either dials an extention or gets transfered by the auto attendant, then when I pick up, the caller cannot hear me until anywhere from 2-10 seconds has passed. The only things that I have noticed that may be related to the problem are the following: 1) It only happens when a caller goes through the auto attendant. 2) The phone is contacting the dns server many many times in each call. (perhaps the caller cannot hear me until the phone finishes this)

I can hear the caller fine but they cannot hear me untill a few seconds have passed. Thanks in advance

I have a VoIP server name in the setup. (Some of the phones may be using an IP address, but they are not all in this building. If having a sever name would cause the problem then I can check them all--I don't see why it would though because the name just leads to the IP address). The phones are set up on DHCP. The phones work fine though until someone goes through the auto attendant so would IP addressing, DHCP or static, have anything to do with it. I am about to go but tomorrow I will change one to static and try some stuff out with it to see if it helps--thanks

I changed 3 phones to static IPs and it seems to have fixed the problem on 1 of the 3

I have the same problem.

You've got an IP issue somewhere in your setup. It sounds like the call is being lost and then the phone is querying the DNS server to find out where it should be looking for the call.

Do you have a VOIP server name or it's IP address in the setup? Are you using DHCP or manually assigning IP addresses? If the VOIP server is not on a static IP, I would fix that first.

Post back here the answers and we can look at it further.

You have an IP issues. You need to see first if you call another phone within your group. Then, go to menu, setting, advanced, password 456, admin settings, networking configuration to see if you have different IP address from the rest of the phone and check the VLAN
