I have recently switched to FreePBX from 3CX and I need help provisioning my IP Phones.
I currently have a Polycom VVX 400 phone and a Yealink T31P phone. I have tried to provision the phones to my FreePBX server which is in the cloud, however, every attempt of provisioning the phones fails and I cannot register it to the SIP Server. I don’t have the smart firewall enabled and I am wondering if it is something that I am doing wrong on my end.
Here’s the configuration of my Polycom VVX Phone Lines below.
This experience overall is very frustrating so if you have any suggestions on how to fix it, please tell me. Thank you!
A couple of quick things to check. On the GUI it shows that Authentication is Disabled. Second thing is to check you are using the correct SIP port. Check in FreePBX as it maybe a different port particularly if you are using PJSIP.
So I’ve done what you did, however it still wont register with the system. I am using the sip port chan_pjsip and changed the port on the phone to 5160 instead of 5060. However I found out that port 5060 was indeed the correct port for it to work. I also tried changing the port type from DNSNAPTR to UDPONLY, yet nothing happens.
Heres my config on the FREEPBX Server:
You also appear to have SRTP enabled, if you don’t have that enabled in FreePBX that could cause a problem. If that still doesn’t work you may need to check the Syslog of the phone or do a PCAP.
