Yealink Forums

Hello together,
I have a Yealink T48G phone and want to use a SIP Phone connection to my provider Telekom Germany.

The phone works fine with incomming calls but I can't call out.
I have contacted my Provider and the settings are ok. No block on outgoing calles.

Register Status: Registered
Firmware Version 35.80.0.125
Hardware Version 35.1.0.2.1.0.0

Please check the attached files:
35.80.0.125_4_29_46.pcap
config.bin

Can anyone help me?

Maybe you should use a stun-Server because i only see private IPs in your pcap
