edinstveno pri zaqvki nasocheni kam port 5060 .


Da se e boril nqkoi sas takav problem?

P.S

Helkp deskta zaqvqvat kategorishno che nqpam filtri

Случайно да си в Стара Загора ?   Там от една седмица има проблем с рутърите, така че VPN и   някои други услуги сред които може би е и SIP не  работят... :(   Иначе без проблем съм ползвал Kphone, но преди 2 мес.,  скоро не съм опитвал. На мен подобен проблем ми прави  Linphone'а 

 A аз открих,че няма пълен NAT в тези модеми и по специално
 по udp protokol. Откъдето са и проблемите... с подобни
услуги...

Ne nesam vav Stara Zagora.


A i ne sam suduren che problema e v NAT
