mediaproxy-ng rtpproxy_answer flags

by Juha Heinanen

let say that mediaproxy-ng rtpproxy_offer had flags SP (RTP/SAVPF was sent to callee). is it necessary to have corresponding flags (e.g. sp) in rtpproxy_answer call or does mediaproxy-ng remember, what caller's profile was when corresponding rtpproxy_offer was called? -- juha

[tracker] Comment added: equals $null and 0 return the same

by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#358 - equals $null and 0 return the same User who did this - Daniel-Constantin Mierla (miconda) ---------- It is not related to #141. I'll try to get a fix for it soon. Meanwhile, one should be able to use the alternatives with: <code> if(defined($avp(x)) ... or if(!defined($avp(x)) ... </code> ---------- More information can be found at the following URL: https://sip-router.org/tracker/index.php?do=details&task_id=358#comment1128 You are receiving this message because you have requested it from the Flyspray bugtracking system.
