Yealink Forums

I have a new Yealink T23G phone connected to a Zultys MX250 v 9.0.4. The phone registers and I can make calls but I cannot receive calls. It looks like a UDP timeout issue. When someone calls the MX250 sends an 4 invites to the Yealink but never gets a response. It should be respond with a 100 Trying then 180 Ringing (as expected). Anyone ever run in to this?

Hi Kyle,

Can you please send a pcap trace, level 6 syslog and config.bin file to us? We will analyze it. This post describe how to get them:
