Does anyone have a better ENUM lookup handler than the built-in ENUMLOOKUP() function? The built-in function does not properly handle multiple return values such as: 8.9.9.3.2.8.8.6.6.8.1.e164.org has NAPTR record 200 10 "u" "E2U+SIP" "!^\\+1866(.*)$!sip:1866\\1 at tollfree.sip-happens.com!" . 8.9.9.3.2.8.8.6.6.8.1.e164.org has NAPTR record 200 10 "u" "E2U+SIP" "!^\\+1866(.*)$!sip:1641641866\\1 at sip.tollfreegateway.com!" . And thus does no...

I'm trying to switch from one call to another incoming call from PSTN. When I'm getting a "beep" I press flash but instead of swithing to the second call, I'm getting a dial tone. even if I press *0, I cannot connect to the second call. Anybody had this problem? Tx, Bogdan

If I have something like: exten => _.,1,LookUp(${EXTEN}) exten => _.,2,Dial(${RESULT}) Then the LookUp function has to deal with making sure the number is properly filled in before returning ${RESULT}.

In at least some cases, I'd also like the order in which the servers in the enum results are tried to be random. The wiki pointed me at enumlookup.agi for enum support of multiple NAPTR results per lookup. By default, enumlookup.agi will either return equal order/priority NAPTRs as a single &'d result, or individual ones in order according to NAPTR defined order and priority. What I'd prefer is for equal order/priority results to be returned separately in the order t...

I've been tinkering with ENUM and found that the lack of a debug message in enum.c that says it has actually succeeded in resolving an address is a bit of a nuisance. It makes it difficult to see if failures with ENUM are due to problems with parsing NAPTR records (in enum.c) or mistakes in extensions.conf An extra line of debug information would be much appreciated!

We know the IP the call is coming from, we can find out from the NAPTR where calls normally go to based on the phone number, if the 2 don't match filter it. -- Best regards, Duane http://www.cacert.org - Free Security Certificates http://www.nodedb.com - Think...
