hey here is my code import logging from pyVoIP.VoIP import VoIPPhone, CallState import speech_recognition as sr import uuid import pywav from pydub import AudioSegment import os import shutil import time

Has anyone managed to get around this error?

[jawad097]

not yet use pjsua 2

[github59173]

Same issue. pjsua2 is great but a pain in the ass having to build the library and haven't been able to build it on windows.

I just stumbled on the same error and captured a traffic with tshark and it looked like that:

and got the same error: TODO: Add 500 Error on Receiving SIP Response.

I saw on Ridit I think some one created the python sip service using pjsua2

[q84fh]

Yup, connection to my SIP server works correctly with pjsua2, but it is no-go for me - because it has dependencies on underlying OS that I cannot satisfy in my situation.

Anyway It would be great to have https://github.com/tayler6000/pyVoIP/pull/216 merged.

Are you facing the problem when record or received the incoming voice from the customer end?
