With a clean installation, i get a lot of deadlocks when try to use MRCPSynth and other commands.

Asterisk Dialplan:

[from-pstn-custom]

exten => s,1,Goto(app-unimrcp,s,1)

[app-unimrcp]

exten => s,1,Answer

exten => s,2,MRCPSynth(Welcome to Asterisk,l=en-US&p=uni2)

Trace:

Do you observe the same behavior with both res_pjsip and chan_sip. I have been mainly experienced with chan_sip but have not done anything extensive with res_pjsip. Maybe you can provide detailed logs for a single call to MRCPSynth that results in a deadlock.

Hi Arsen.

In my asterisk whenever I use mrcpsynth i can see in the asterisk log that kind of messages while synth is in progress. I'm using chan_sip.

Let me know how can I send you a log file, as long as this discussion group does not allow attachments other than images.

Thanks in advance.

Carlos

It would make sense to open a new issue in the GitHub project and upload all the related details there.
