The windows XP PJSIP (version 0.5x) is able to talk to regular phone over PSTN gateway. But it becomes one way voice after 10 minutes conversation. The PJSIP is still able to heard the voice from the PSTN side, but the PSTN side cannot heard the voice from PJSIP windows side afte 10 minutes. Did anyone this this problem before? The eyebeam did not have this issue over the same PTSN gateway. Thank, UN. -------------- next part -------------- An HTML attachment was scrubbed...
