Hello Benny, Thanks for your response. Actually when I check my packets on wireshark I get a '401 unauthorized'. In the sip message I get the following: (PJSIP_ENOCREDENTIAL) [status=171101] When I checked the web site link on PJSip it said this: No suitable credential is found to authenticate the request against the received authentication challenge in 401/407 response. This often is caused by different realm supplied in the credential than the realm found in the challenge. The realm I am currently using is 'asterisk'. So maybe this is not the correct realm to use. Actually I am not sure what is is supposed to be. When I put '*' I get response 600, so maybe the * is ok. What is the reason for putting in a '*' for the realm?
