I have been clawing my way through PHP files trying to understand how this is happening. I am not necessarily looking for an answer (unless you have one) but hopefully someone either has seen this problem before or can point me to the right files(s) to figure out where this DID is being mangled.
I changed the phone number to protect our privacy.
If I enter 2677989900 into the “DID Number” field in Inbound Routes, click SUBMIT then APPLY CHANGES the number will be incorrectly written to extensions_additional.conf as the following:
exten => -1616979496,1,Set(__FROM_DID=${EXTEN})
exten => -1616979496,n,Gosub(app-blacklist-check,s,1)
exten => -1616979496,n,ExecIf($[ “${CALLERID(name)}” = “” ] ?Set(CALLERID(name)=${CALLERID(num)}))
exten => -1616979496,n,Set(__CALLINGPRES_SV=${CALLERPRES()})
exten => -1616979496,n,Set(CALLERPRES()=allowed_not_screened)
exten => -1616979496,n(dest-ext),Goto(ext-queues,4800600,1)
However! If I put a “_” before the number ("_2677989900") then I get this output:
exten => _2677989900,1,Set(__FROM_DID=${EXTEN})
exten => _2677989900,n,Gosub(app-blacklist-check,s,1)
exten => _2677989900,n,ExecIf($[ “${CALLERID(name)}” = “” ] ?Set(CALLERID(name)=${CALLERID(num)}))
exten => _2677989900,n,Set(__CALLINGPRES_SV=${CALLERPRES()})
exten => _2677989900,n,Set(CALLERPRES()=allowed_not_screened)
exten => _2677989900,n(dest-ext),Goto(ext-queues,4800600,1)
Adding a “_” implies to me a type-cast to a string rather than a numeric value. The ‘-’ in ‘-1616979496’ indicates to me the number has skipped some kind of sanity check and has been type-casted to an incorrect numeric type.
I have checked mysql->asterisk.incoming and verified the DID appears correctly. I also did a var_dump in libraries/extensions.class.php to confirm “functions add” is receiving the right DID but someplace further down the line it is mangled.
I can also confirm this DID is the only one out of 300 DIDs experiencing this problem. This scares the hell out of me because it means something is broken somewhere and I don’t want to wait until something much more serious breaks to find out how far the cancer has spread. I can’t reproduce this problem on any other FreePBX installation or even this installation. It seems to be limited to one specific number.
Thank you for any help you can provide.
