Polycom phones behind barracude load balancer

Hi Sir,

           I have polycom phones which is registered to Barracude allocated load balancer IP. Now when i make a simple call from any SIP phones to a polycom phone noramlly all SIP request and response need to pass through Barracuda.But here when SIP INVITE request reaches to Polycom phone and when polycom phones sends final response (call answered) is getting routed to registrar via router and not by Barracuda. Hence all response or requests sent by polycom phone are getting routed via router to registrar and not by Barracude.

         Can you please let me know why such behaviour is shown by Polycom phones? If i do same scenario from any other SIP phone to any other SIp phone all SIP request and response are flowing through Barracuda as expected behaviour.

 

Thanks,

Sarath Sundar

Hello Sarath,

welcome to the Polycom Community.

Not knowing what phone models or even the used software makes it difficult for yourselves or others to check against release notes for known issues.

 

This kind of troubleshooting would require to check the phones logs and also have a wireshark trace documenting the signaling and negotiation of this.

 

As this is outside the scope of the community, due being a support issue, I suggest you contact your Polycom reseller and/or Polycom support directly to raise a case.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Re: Polycom phones behind barracude load balancer

HI,

 

My question in brief:

 

Currently, all polycom phones were routing responses to the first VIA header values from the request. Is there any provisioning configuration parameters to make them route them to request source IP and port?

 

If you want any infomation, we will provide the trace of a call.

 

Thanks,

Issue with polycom vvx 500 diectory.xml file

Hi,

     I have a polycom vvx500, now when i provision the phone for the first time via FTP server, phone is reading every configuration file. The issue is tha when the phone is rebooted for the second time. The phone is unable to read the contact directory (mac.directory.xml file. The phone configuration file is as follows:

 

<APPLICATION_VVX500 APP_FILE_PATH_VVX500="Worldsmart_VVX500-4.0.ld" CONFIG_FILES_VVX500="0004f2813363-reg-advanced.cfg, 0004f2813363-reg-basic.cfg, 0004f2813363-features.cfg, 0004f2813363-region.cfg, 0004f2813363-sip-basic.cfg, 0004f2813363-sip-interop.cfg, 0004f2813363-site.cfg" MISC_FILES="Worksmart.bmp, Worksmart400.bmp" LOG_FILE_DIRECTORY="pbx-dev/logdirectory" OVERRIDES_DIRECTORY="pbx-dev/overrides" CONTACTS_DIRECTORY="pbx-dev/contacts" LICENSE_DIRECTORY="pbx-dev/licenses"/>

 

If we make any changes in the contact directory, the changes are not getting reflected from the second reboot onwards.

The above fomat is common and working for other polycom phone types. The issue is only with polycom vvx 500. I have upgrade the firmware to 5.0.1 version and issue still remains the same.

 

Please let us know what could be the issue.??

 

Thanks,

Sarath Sundar

Hello Sarath,

 

I had twice responded that you need to get this to the attention of Polycom support.

 

Please contact your Polycom reseller.
