Hello, Looks like our new sip provider may have uncovered another issue. Using our other sip provider does not seem to cause the same issues, even with much higher calling volume. I am running the latest version of pjsip. The problem is in pjmedia_jbuf_put_frame2. It is getting stuck in the while loop. I'm not sure how useful this will be but I am going to attach a few of the details from gdb. I can see why it is looping, but it is not clear to me how it got into this state. The one thing that jumps out at me is the jb_frame_ptime = 10. I am using a ptime of 20, and the new sip provider does as well. Is this unusual? Any insight into this issue would be greatly appreciated. -- Michael Broughton, Advanis Unintended Recipient & Unauthorized Use of E-Mail: This message and attachments may contain confidential or privileged information that is intended only for the named recipient of this e-mail.
