In blind transfer, the transfered does not hear the ringtones

Hi Polycom Community,

I have the next problem, when a phone makes a blind transfer the transfered dont hear the ringtones, better explained in a schema

We have a caller / transfered A, a called B the transferer and a called C


A calls B

B rings

B answers

B push the transfer button then the extension of C and then transfer again (blind)

During the process A heard music on hold

C rings

A doesn't heard ringtones think that the end hangups when C is actually ringing

if C Answer, A can hear the voice and talk perfectly


We don't know when this start to happend, but before this work as a charm.


I have a park of about 3000 phones composed of :

 

Model        UC Software Version

IP 300       2.1.3.0028

IP 330       2.1.3.0028

IP 331       4.0.4.2906

IP 335       4.0.4.2906

IP 500       2.1.3.0028

IP 550       4.0.4.2906

 

I can provide network traces or the logs of the phones or other things, if it is necessary

 

The english isn't my native language so sorry if there are some mistakes in the post

Hello policom <3,

welcome to the Polycom Community.

 

This is most likely a signalling issue as under certain circumstances when we receive a 183 message but no media there won't be any ringing sound.

 

We usually create our own ringing tone for a 180 message.

 

In order to troubleshoot this you could use wireshark.

The community's VoIP FAQ contains this post here:

You could post logs or traces here for other community members to look at but if you require support your Polycom reseller would need to raise a case with our Polycom support Team.

 

If the units are out of warranty you would be required to pay per incident.

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

Best Regards
