Description

Hi, We have installed the Goautodial V4 on our server, according to the CentOS7 guide. and have done all the changes mentioned there, But when we dial the number call gets connected but there is no sound on both sides, we have tried alot of methods but unable to solve it if we press hold button the person on phone end hears the music but he cannot hear the agent and agent cannot hear the person, we have tried this in manual dialing mode.

Any help in this regards will be helpfull, we have sorted the tls issue and we have installed our domain SSL certificates properly.

We are using our Freepbx sip trunk on goautodial.

both servers are inhouse.

I have attached my Kamailio.cfg , rtpengine.cfg

My go autodial server ip is : 192.168.10.25
My external domain is: mydomain1.dyndns.org

Here below is my Kamalio.cfg:

  1. For REGISTER requests we hash the Request-URI, Call-ID, and source IP of the
  2. request into the nonce string. This ensures that the generated credentials
  3. cannot be used with another registrar, user agent with another source IP
  4. address or Call-ID. Note that user agents that change Call-ID with every
  5. REGISTER message will not be able to register if you enable this.
    modparam("auth", "auth_checks_register", 11)
  1. For dialog-establishing requests (such as the original INVITE, OPTIONS, etc)
  2. we hash the Request-URI and source IP. Hashing Call-ID and From tags takes
  3. some extra precaution, because these checks could render some UA unusable.
    modparam("auth", "auth_checks_no_dlg", 9)
  1. For mid-dialog requests, such as re-INVITE, we can hash source IP and
  2. Request-URI just like in the previous case. In addition to that we can hash
  3. Call-ID and From tag because these are fixed within a dialog and are
  4. guaranteed not to change. This settings effectively restrict the usage of
  5. generated credentials to a single user agent within a single dialog.
