BLF issues.

[Anonymous]

Hello Community!

I'm having an issue whereby, we register the phone to a load balancer, this then assigns a sip server from a pool of 4 servers - all of which has presence enabled.

If I register to a specifc sip server,  I can receive status updates through presence about other phones on our network on my VVX310 . But, if I point at the load balancer, then I cannot receive updates like - phone ringing, phone busy etc

Do you know, why this might happen, only for Polycom phones, and no others (Snom, Yealink, Grandstream etc....)?

Many many thanks!

Just to add to this, the line keys monitoring other extensions, are monitoing for a specific amount of time, then it seems like they're timing out. I  think this is to do with DNS settings on the phone, but still haven't worked out how to configure the VVX310 to keep this registration and not poll for a new one, therefore breaking the presence relationship.

Any help would be great, even just a hint at where to start looking.

Cheers, Joe

Ensure your FTP / HTTP Server allows to append the logs and ensure the Upload Append Size Limit (Kbytes) is set to at least a couple of megabytes.
