I’m trying to set up pjsip to work with an obi202 and google voice. But I can’t configure the endpoint.

pjsip:

[obi202-auth](!)
type = auth auth_type = userpass password =

[obi202-aor](!)
type = aor max_contacts = 2

; ===== endpoints ========

[gv-voice](obi202-endpoint)
auth = gv-voice aors = gv-voice identify_by=auth_username
;identify_by=username ; I also tried this. Same result. context = gv-voice

[gv-voice](obi202-auth)
username = gv-voice

[gv-voice](obi202-aor)

##############

From the pjsip logging:

Any help appreciated.

  • I’m expecting gv-voice to be the “matching endpoint”. The INVITE has gv-voice as the “Contact:” . Isn’t this the “Username” in pjsip “auth” ?

    —

  • Nope. The Contact is never considered for that. The From username is what is matched for an endpoint using the “username” option. The authentication username is what is matched for an endpoint using the “auth_username” option but you also need to ensure it is enabled in “endpoint_identifier_order” global option. This also requires the endpoint to actually authenticate.

  • Thanks for the reply.

    auth_username seems to be enabled:

    asterisk*CLI> pjsip show identifiers Identifier Names:
    name not specified ip username anonymous header auth_username

    Is the order a problem ?

    I set:

    endpoint_identifier_order=auth_username,”name not specified”,ip,username,anonymous,header

    restarted. No errors.

    But no effect on the identifier order.

    From obi202 :

    SIP Credentials Parameter Name Value AuthUserName gv-voice AuthPassword password

    Not sure what this means. Of course, I agree, but how do I make this happen?

    BTW, this is 16.3.0.

  • So you’re using the obi with 2 itsp accounts, one Google Voice and the other Asterisk yeah? Then forwarding calls between them?
    Are the credentials defined in the gv-voice auth object also configured in the obi account that points to Asterisk? Is the obi registering successfully to Asterisk?

    In this situation it might be better to treat the OBi like an ITSP in Asterisk. Instead of using registration and userid/password authentication, add an “identify” object that matches on the obi’s ip address and points to the gv-voice endpoint…

    [gv-voice]
    type = identify match = /
    endpoint = gv-voice

    This way you don’t need to set up any auth objects at all and you just need to set “identify = ip” on the endpoint.

  • The obi may not be at the same ip address. I use it when I travel.

    But this was solved. It was the identifier order.

    2 points for anyone with this issue:

    “endpoint_identifier_order=” must be in a [global] section, and needs
    “type = global” .

    Also, pjsip reload won’t make the change, you need to restart.

    WFM now !

    Thanks for all the help.
