Thanks Adrian,

We are able to proceed but again stuck at with error "AttributeError: /usr/lib/x86_64-linux-gnu/libgnutls.so.28: undefined symbol: gnutls_certificate_verify_peers3"

Actually we updated sipsimple and then try to start sylkserver but that time we observed error for libgnutls and it was saying libgnutls is not found at your system so installed libgnutls28.

Apr 23 11:01:36 gitserver sylk-server[7682]: RuntimeError: cannot find libgnutls on this system

After this libgnutls28 installation as said we have below errors.

Below is error log.

You must upgrade python-sipsimple package.

I need some assistance in installing sylkserver.

Actually we install the sylkserver with apt-get and also source code on our Ubuntu 12.04 machine but when we start the service we observed below error and unable to proceed further.
