Hi John,

Thanks for the reply, we have been following up with sangoma but we didn't
get any solution or workaround from them.
We hoped to find resolution from people who may have faced the same issue.
Any insight much appreciated

Thanks
Abhishek

I would imagine you would get better answers by speaking to Sangoma.
