Solved 3CX v15 and Polycom IP 550

[Wolfraider]

We are running 3CX v15 and have several Polycom IP 550's. They phones provision fine but we cannot call out. We get a busy signal when trying to call other extensions or voicemail. Inbound calls work fine. The phones are running firmware 4.1.0.84959.

Hello @Wolfraider

Are these phones provisioned as local extensions to the PBX using the default templates? Are the phones and the PBX in the same network ?
Have you tried enabling PBX delivers audio under extension settings and see if that makes a difference?

Have you looked at the dial plan on the polycom 550?

 

[Wolfraider]

Local extensions with the default template
same network
I checked the PBX delivers audio and no difference

Digit Map is empty on the phone

I'm going to do a wireshark to see if the phone is trying to send any packets out when trying to call

Tried a different phone and it worked fine. Looks like for some reason I have a dead phone.

format Polycomes file systen (not just reset) and boot it up with DHCP option 66, it will reload the sip firmware and provision. does this solves the issue???

That fixed it, thank you
