Dear all: I have a question about google voice. I can call a number via google voice as following: sip => FS => GVoice => Phone. The question is that, I can call two different phone numbers with two different sip accounts via the same GVoice account. Is it a normal situation? I am worried about that google will ban my IP or account if I call several numbers simultaneously via one GVoice account. I tried to login with two GVoice accounts. My client.xml is as following: *<include>* <profile type="client"> <param name="name" value="GV1"/> <param name="login" value=" GV1@gmail.com/gtalk"/> <param name="password" value="PWD1"/> Other settings… </profile> <profile type="client"> <param name="name" value="GV2"/> <param name="login" value=" GV2@gmail.com/gtalk"/> <param name="password" value="PWD2"/> Other settings… </profile> *</include>* * * FS will crash. The error message is: Assertion failed! Program: C:\FreeSWITCH\FreeSwitch.exe File: ../../../src/libgcrypt-1.4.6/src/ath.c Line: 193 Expression: *lock==MUTEX_UNLOCKED Sincerely yours, Thisjoy.
