sip - WebRTC to make calls to PTSN -


i'm looking @ webrtc , i'm wondering how implement solution client connects ptsn via sip. seems pretty new technology assume not work on ie browsers; correct?

basically, have dialpad ui on page , users have sip account. can webrtc enable end-user make calls ptsn , take implement such solution?

i'm looking alternative java or flash based webphones.

thanks suggestions.

webrtc indeed new , isn't available on ie or safari. available in beta/alpha on other browsers. ie support in future , safari won't time.

webrtc media parts of negotiation, , such means no signaling of own. sip can work webrtc, need js implementation of sip (over websockets) , you'll need unwrap sip signaling on server side , "migrate" udp or tcp. asterisk working on such server side platform: http://blogs.digium.com/2012/05/23/asterisk-11-webrtc/

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
