[asterisk-bugs] [JIRA] (ASTERISK-23191) Cannot get local SDP on incoming calls (WebRTC)

[Jay Jideliov (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=214759#comment-214759 ] 

Jay Jideliov commented on ASTERISK-23191:
-----------------------------------------

Additional info that my help in troubleshooting this issue.


We are trying to establish a DTLS-SRTP-encrypted connection. On the outgoing call, we can see the following in the INVITE:

m=audio 50152 UDP/TLS/RTP/SAVPF 109 0 8 101

However, when Asterisk is bridging the connection, it sends the following INVITE:

m=audio 19798 RTP/SAVPF 0 3 8 101


However, SIPML5 is expecting UDP/TLS/RTP/SAVPF in the "m=" field. 

Therefore, SIPML5 refuses the cooection with 603 Failed to get local SDP.

> This is an issue created as a follow-up to this comment (https://issues.asterisk.org/jira/browse/ASTERISK-21930?focusedCommentId=211742&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-211742) as well as due to us having the same issue when trying to receive incoming calls via WebRTC.
> Asterisk 11.7 + SIPML5 + WSS, both Firefox and Chrome.
> Devices register fine, and are able to make outgoing calls. However, the issue arises on incoming calls, when all we get is the error (cannot get local sdp) after which the line disconnects.
