Dear Support,

We are using IPTEL SIP services. Now we are getting Error message on our VOIP software is “ Server sip.iptel.org did not respond to register”.

Moreover, we can successfully ping and complete trace route the sip.iptel.org from our server but failed to register through sip.iptel.org server. Kindly suggest what is the cause and look into this matter. I am sending you our IPTEL SIP ID/Username and please find below.
