I am having two PBX connected together say PBXA and PBXB. PBXA i am having users 10001,10002,10003 and trunk called 20003 which is registered to PBX_B. PBX_B also having sme users 10001,10002,10003 .
PBX_A ==> 10001,10002 ,10003
PBX_B ==> 10001,10002,10003
Now when i am calling PBX_B to PBX_A using trunk 20003 by 10001 user it is giving me 403 forbidden error in PBX_A . And in asterisk console am getting the error like this.
If i am making any other user in PBXB which is not in PBXA i am able to make calls and it is working fine.
“chan_sip.c line:11375 func: check_auth username mismatch, have <10001>, digest has <20003>”
Thanks in Advance
