Polycom RealPresence Trio - Audio Problems

[Anonymous]

Hi.

I have a new Polycom RealPresence Trio to setup on my organization, but I have some problems.

I configured the iptables to opening 1720 (TCP and UDP), 5060 (TCP and UDP), 5061 (TCP and UDP), 3230:3243 (TCP), 3230:3285 (UDP), 2222:2269 (UDP) and 10000:32767 (UDP) ports for Polycom receive external calls.

When I try to call to Polycom from external networks, I can get the call and answer on Polycom (the call is established) but on

Polycom or external equipment (Polycom's mobile app or Windows software) can't hear.

I already sniffing the call packages with the wireshark and I see the communication between devices on the ports that already opened.

Anyone can help me with this?

Thank you.

Hello tk_luisdourado,

welcome to the Polycom Community.

It is always useful to include the currently used UC Software version as issues experienced may already be addressed in a newer release.

Please also include if you are using a SIP server or a LYNC / Skype for Businessserver

This also allows yourself and others to check against current software release notes.

The above is also stated in the "Read First"

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP UC Software Version or the BootROM Version of my Phone?
Resolution: Please check here

Hello tk_luisdourado,

Your first task should be to upgrade to a currently supported version which at present is UC Software 5.4.3

You can do this via the Web Interface or the VoIP FAQ contains this post here:

Resolution: Please check => here <=

In addition you may want to check this here:

Resolution: Please check => here <=

Obviously the SIP Signalling (5060) ports and then the negotiated RTP ports need to be able to pass any firewall.

I am not sure what other devices apart from the Real Presence Desktop app you are using but a local PC Firewall may block this to.

The RealPresence Trio8800 itself was sold via VIDENDA DISTRIBUTION LIMITED back in 29/01/2016 so you may want to work with them on First Level Support before escalating via them to Polycom support.
