Hello,

We really do not see any majorly concerning issues and it seems very isolated as to who is experiencing issues.

This is not a capacity / load issue as the load and demand on the current proxy is very low and processing as normally expected.

sip:~# uptime
20:04:34 up 140 days, 21:11, 1 user, load average: 0.08, 0.04, 0.01

However we've setup an additional proxy in an alternate network segment to see if you guys have better connectivity to this server.

You can swap out your proxy from "sip.voipwelcome.com" to "sip2.voipwelcome.com"

Please do let us know how this works out for you, thanks!
