Register SPA502G remote proxy

[ebrahim.m@exoticcolors.me]

Hi, I'm Using SAP502G Cisco IP Phones normally with Third Party PBX provider inside the same network, Last week i purchased "Proxy" license from the PBX provider it makes me register the phone from other location and networks using this proxy and i can make calls from outside the network using the PBX in the other location, However, I'm trying to register the phone by using this proxy as TLS protocol but it's not working with me, I don't know if there is any process i should change to let my phone works since i tired the proxy with other IP phone Brand and it works with me. 

Any solutions please??

It's not working ... - somewhat vague description of the issue, isn't it ? Turn on syslog&debug messages of VOice application and capture them:

Debug and syslog Messages from the SPA3xx, SPA5xxG, SPA9xx, & WIP310 IP Phones

It will help you/us to identify the issue cause.

As a pure blind shot - proxy in question is using TLS certificate issued by CA you didn't configured as trusted. Secure connection can't be established as a result. Use "Custom CA RULE" configuration option (Provisioning tab) to import CA certificate into trusted certificates store. Remember - it's just blinds shot hint based on "it's not working" description of the issue ...
