> Key: ASTERISK-27763
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-27763
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Resources/res_pjsip_session
> Affects Versions: 13.20.0
> Environment: CentOS Linux release 7.4.1708 (Core)
> Kernel 3.10.0-693.17.1.el7.x86_64
> Asterisk 13.20.0
> Reporter: Thiago Coutinho
> Severity: Minor
> Labels: fax, pjsip
>
> Some providers send T.38 streams along with the call (I don't know why) causing PJSIP to reject the call. chan_sip on the other hand accepts the call normally.
