[reSIProcate-users] Help - Facing problem to send sip message towards proxy

Hi Scott,

 

Hope you are doing good.

 

Thanks for your previous suggestion. I’m facing another issue while enhancing my application.

 

I have tried to integrate StackThread class in my application by referring stack/test/testStack hxx and cxx files with some minor configuration changes in transport ports. I have taken two SipStack pointers each for receiving, sending and assigned 2271 as receiving port and 2272 as sending port.

 

When i make a call, I'm receiving the message to application and able to process successfully. But when i'm trying to send new request from application, i'm getting this below error

 

ERR | 20170712-134943.117 |  | RESIP | 140053664692192 | DataParameter.cxx:91 | Accessing defaulted DataParameter: 'tag'

B2BServer: DataParameter.cxx:93: virtual std::ostream& resip::DataParameter::encode(std::ostream&) const: Assertion `!mValue.empty()' failed.

 

When i debugged this i got to know this error is for headerEnum 11, which is of Contact header. Though it is of NameAddr type, tag is not mandatory parameter for Contact right?

 

I'm providing complete output in the attached file ‘Stack_Error2.txt’ . Can you suggest some clue to resolve my issue if i'm doing anything wrong.

Can we use same SipStack pointer with only one transport to send and receive sip messages which are out of transaction?

 

Also I have few queries in StackThread class. As per your previous comment, process() should be in loop, i couldn't find explicit while or for loop in the file.

Does these statements runs in loop?

 

receiver->process(fdset);

sender->process(fdset);

 

Could you explain how its working?

 

Thanks & Regards,

LavanyaKumar S

You need to process in a loop.  Check out stack/test/testStack and other programs in the test directory.   You can use StackThread class to help.

 

There is also info on the wiki for this:  http://www.resiprocate.org/DUM_Threading

 

Just ignore the DUM parts of the wiki page.

 

Good luck,

Scott

Hi,

 

I'm new to resiprocate. I'm trying to send an INVITE request from my linux machine. I'm able to generate a SIP message. But unable to forward to my proxy with the details filled in Route header. My requirement is to use resip but not dum as our application will handle session.

 

Here i'm attaching my code and output. Not sure whether i missed something.

 

Could someone please help probably with some sample references or examples.

 

We are using resiprocate-1.9.10.

 

Thanks & Regards,

LavanyaKumar S
