Question about Polycom SoundPoint IP 501 IP Phone

2 Answers

For incoming calls, the caller cannot hear me for 2-10 seconds after I pick up

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

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

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.

SOURCE: Polcom phones stop ringing

Dear Sir/Madam,

1) After rebooting you can watch your ftp server and see the phone logging in and logging out. Its doing several things (checking the size of the bootrom.ld and sip.ld files and seeing if an update is necessary, etc etc) that I will go over later. It will reboot a couple of times to finish off the update.

2) After the reboots, lets be absolutely sure and lets check the bootrom and SIP versions.

  • Press the Menu button, 2 Status, 1 Platform, 1 Phone. Arrow down to view the BootRom version here.
  • Press the Menu button, 2 Status, 1 Platform, 2 Application, 1 Main. You will be able to view the "Version" number here.

If you did everything right, you should see the latest versions of the bootrom and SIP app that you had placed on your ftp site.

Now check your FTP site. You will notice that there are files being uploaded to your directory with *.log extensions. You guess it, these are just logs that the Phone dumps so you can trouble shoot when need be. If everything was done right, your phone will of seen the new bootrom.ld file and downloaded it, rebooted, and installed it. Next it will download your new sip.ld file and use it.



For More Information and Software updates. See this link.......

Ohh this mean, you did not register this extension on your phone system. Create this extension on your phone system. Be sure that password given on Phonesystem is also configured on phone too.

SOURCE: Polycom Soundpoint IP 501 - URL call is disabled

This in it's most basic description means that the phone is unable to register with the SIP server, most likely for lack of internet connectivity or a firewall blocking the packets.

If you've verified connectivity and opened the proper ports and the phone fails to initialize and still getting “URL Call Disabled” or all of the above parameters are correct, update the firmware for the router. This can usually be done within the router configuration. Then reboot in order, the cable modem or DSL, the router or switch, then the phone. This may solve the problem.

If still having the same issue, confirm in the router configuration for settings such as SIP proxy, gateway, or application layer or any configuration setting for SIP or VOIP. If any of these do exist, make sure they are turned off as these may only confuse or adversely affect many implementations.

I use polycom Sound Point IP 550 phone. For an incoming or outgoing call after some duration the other end of the caller is not able to listen to me. However I can listen to them, once understanding that...


This sounds like an RTP stream issue. While SIP runs on port 5060 by default, the actual audio is run on much higher ports, 10000 and up. If your pbx system is not on a public address and you are forwarding traffic to your pbx via a router, check the RTP port range in your pbx and make sure you are forwarding those ports correctly. By putting the call on hold, you stop sending out audio traffic restart sending audio when you pick the call back up. By forwarding the entire RTP range to your pbx, this should fix your issue.

Polycom SE225: my verizon line provide caller id does not displa


Due to the age of the SoundPoint Pro, it some of its features are not compatible with newer phonesystems, such as CableVision. There are no software updates for the SoundPoint Pro, and as long as the Caller ID is enabled there are no other settings or adjustments that can be made to workaround these kind of problems unfortunately. I recommend contacting your service provider to see what kind of caller ID signaling they are using; most likely they will be using a newer digital system, or MDMF which is not backwards compatible with SDMF or earlier CID receivers.
