Not properly transferring to voicemail in FOP2

  1. 8 years ago

    I am having an issue with transferring calls to voicemail using FOP2. We are using 4 digit extensions (5558 for example) but when I go to transfer to voicemail, it says "The person at extension 58 is I'm sorry. That is not a valid extension." and then it hangs up. Any assistance with getting this fixed would be appreciated.

    If you use FreePBX, the extension prefix to transfer to voicemail is derived from MySQL tables set by FreePBX directly. It does not care if you have 4 or 10 digit extensions. Run this:

    /usr/local/fop2/autoconfig-buttons.sh

    inspect the output from one SIP/xxx extension, you will see a header named "extenvoicemail". consider its value, this is a sample definition:

    [SIP/1604] type=extension extension=1604 label=John mailbox=1604@default context=from-internal queuechannel=Local/1604@from-queue/n|Penalty=0|MemberName=John|StateInterface=SIP/1604 customastdb=CF/1604 extenvoicemail=*1604@from-internal queuecontext=from-queue autoanswerheader=__SIPADDHEADER51=Call-Info=answer-after=0.001

    How does extenvoicemail looks on your own config? Does it look correct? ( a prefix + extension number) ?

  4. Admin,
    Thank you for your help. When we checked our settings, they were the same as your screenshot. After some further digging, we found that there was a feature code enabled *55 to disable intercom. Our extensions were 5500-5599. When we disabled the *55 feature code, it worked.
