esip's Introduction

eSIP

ProcessOne SIP server component in Erlang.

Building

Erlang SIP component can be build as follow:

./configure && make

It is a rebar-compatible OTP application. Alternatively, you can build it with rebar:

rebar compile

Dependencies

Module depends on fast_tls and as such you need to have OpenSSL 1.0+.

Please refer to fast_tls build instruction is you need help setting your OpenSSL environment: Building Fast TLS

Development

Test

Unit test

You can run eunit test with the command:

$ rebar eunit

esip's Issues

Package not found in registry

If we compile under rebar3, than Rebar3DepsFilter rewrites deps from git format to hex format.
Rebar3DepsFilter is too aggressive. Not all tags are present on Hex.

The transformation should be optional.

Error example:

./rebar3 compile
Package not found in registry: fast_tls-1.0.17

esip_dialog prepare_request should include from and to "display name"

on line 162 and 163, the header From and To should contain display name but not <<>>, the display name should get from INVITE.

Remove erlang:now/0 deprecations

Here are the deprecations:

rc/esip_transaction.erl:224: Warning: erlang:now/0: Deprecated BIF. See the "Time and Time Correction in Erlang" chapter of the ERTS User's Guide for more information.
src/esip_transaction.erl:226: Warning: erlang:now/0: Deprecated BIF. See the "Time and Time Correction in Erlang" chapter of the ERTS User's Guide for more information.

feature request: 2-way tls for esip

Is it possible to include 2-way mutual tls for esip connection?

esip_transport can not really drop message_out callback

at line 80, if callback function message_out return drop, it just give can not encode "ok".

esip_codec:encode_via not check member value =:= undefined

For example, if host =:= undefined, it just encode record with some atom undefined, the encode returns ok, and it's result can not transfer to binary or send with udp port. I think it should return error, or just encode "undefined" to some string but not an atom.

balance udp traffic over the process pool

It might be a better idea to use a random distribution for the received udp packages instead the one that sends the packets from the same ip, port pair to the same process.

In case all the traffic comes from a sip proxy (very common use to balance sip traffic) only one process is used to handle the traffic and all other 99 are idle.

get_proc_random() ->
    {_, _, MicroSecs} = os:timestamp(),
    get_proc((MicroSecs rem get_pool_size()) + 1).

Instead:

get_proc_by_hash(Source) ->
    N = erlang:phash2(Source, get_pool_size()) + 1,
    get_proc(N).

Provides a significant performance boost.
