When calling from an XLite softphone to a Callcentric number which has an Asterisk PJSIP channel registered, we cannot hear anything at all on the softphone (though the call is indeed established).
Note that everything works fine if:
- The call is initiated by Asterisk
- We use Zoiper as a softphone client
- We use chan_sip instead of pjsip in Asterisk
- Asterisk is registered to a different provider, such as nexmo or didlogic
