Re: [OpenSIPS-Users] Managing the implicit subscription and its NOTIFYs within B2BUA REFER handling

[Vlad Patrascu]

Hi Jeff,

Sending NOTIFYs is supported by using the "n" flag for the b2b_bridge() 
[1] function. Just note that some mechanisms from RFC 3515 2.4.4 
 are not 
implemented though, such as the ability to terminate the subscription 
prematurely by unsubscribing or refreshing the subscription.

I have a need to write some REFER handling functions into an existing 
OpenSIPS SBC stack, and I need to send accurate NOTIFYs back to the 
REFER-er.  Terminating the subscription with the first NOTIFY isn't 
good enough, sadly.  I'm hoping this is the right way to do it.

Re: [OpenSIPS-Users] iOS 15 WebRTC

[Bogdan-Andrei Iancu]

Hi Callum,

The error logs translates into "not able to get a full SIP message 
within 4 read operations from the network". What is puzzling is the fact 
you claim that the REGISTER is actually successfully read and processed 
by OpenSIPS - if this is correct, maybe there is some other data on the 
connection, something else than the SIP packages, maybe some CRLF 
pinging that triggers this.

Do you have pcap on that connection ?

Best regards,

Hi All,

I'm wondering if anyone in the community has encountered the iOS 15 
WebRTC bug as reported here:


https://www.wowza.com/community/t/ios-15-webrtc-problem/93868/4 

https://developer.apple.com/forums/thread/689293 



The bug causes INVITES to fail to be digested by opensips with a log 
message as shown below:


opensips[217976]: ERROR:proto_wss:ws_process: Made 4 read attempts but 
message is not complete yet - closing connection


Worth noting is that REGISTER messages still arrive so as mentioned in 
the article is does appear related to fragmentation of the messages 
being sent through, perhaps failing to conclude this for reassembly 
but I can't make sense of the network trace.


My client device is using SIP.js and I can confirm that it continues 
to work on Android and other iOS versions. I'm currently running 
opensips 3.0.5 and would happily upgrade to the latest version if 
there was anything worth trying or wolfssl has any potential to 
resolve this issue!


Thanks,

Callum

Re: [OpenSIPS-Users] OpenSIPS Control Panel missing table?

[Bogdan-Andrei Iancu]

Hi Pedro,

For OpenSIPS 3.2 better use Control Panel 8.3.2 [1], not master. The 
master is under heavy devel (future 9.3.2).

Hello Friends, installed opensips 3.2, opnesips-cli, and opensips-cp 
all from master branch using git….. all seems to be working fine, but 
the Control Panel….after installing the DB schema (mysql) and 
configuring the database, I get this error on almost every module 
“Table 'opensips.tools_config' doesn't exist )”.


I checked all the documentation but can’t find this table 
anywhere……can someone point me in the right direction?


Also, generating the script for trunking, it looks like it creates it 
but can’t find it anywhere.


Thanks,
