Connect asterisk with HuaweiSoftX3000 via SIP. After incoming call from Huawei got disconnection tone. (But by another provider it’s works fine).
pastebin.ru/7707 - here is sip, rtp and rtcp debug at all.

Try to make 1.2.14

Call from PSTN to Asterisk: pastebin.ru/7751 (hear in PSTN phone busy tone)
Call from PSTN to XLite pastebin.ru/7752 (hear fine - all works)

Please help me. How to solve a problem with it:
