Hi Yasin,

I would like to use teksip as registrar to troubleshoot IMS phones. I have added my sip username (001001123456789@191.168.0.1) as endpoint in Teksip. But phone receives unauthorized message and tries one more time and my phone crashes finally with 200 OK mesage. Do you think I'm missing some settings? Here is the log. (Due to max size restriction I have skipped the message of the 2nd attempt)

Hi,

Have you defined endpoint's SIP ID as 001001123456789@192.168.0.1 or 001001123456789 in TekSIP?

Best regards,

Dear Venu,

Although your initial REGISTER request contains Authorization header, nonce and response parameters are null. That's why you get 401 response until
this paramters properly populated.

Best regards,
