We are using append_branch for parallel forking. Sometimes we fork calls to a maximum of 6 phones,
which includes IP phones as well as PSTN phones. We are dynamically adding branches, which are
fetched from database. A module is written for this, and the script just relays the call.

Can anyone explain more about this? I am curious about this because we are forking calls to both
PSTN gateways and IP phones. We got both PSTN and IP phones ringing at the same time and haven't
faced any issues so far with this.

AFAIK, append_branch is the only mechanism SER provides for parallel forking. As i said, we
haven't faced any problems with this approach.
