Can anyone help me finding greengrassV2 connectors for the below listed protocols. I have been searching for them.
IEC 60870- 5-101
IEC 60870-5-103
IEC 60870-5-104
DNP3.0 TCP/IP

I am doing research on CAN BUS and CAN Protocol. I want to know that, does each car model has different pinout on OBDII port? Or Is it same on all cars?
P.S. If it differs, is there a database for it?
Wikipedia to the rescue:
OBD-II is an improvement over OBD-I in both capability and standardization. The OBD-II standard specifies the type of diagnostic connector and its pinout, the electrical signalling protocols available, and the messaging format.
AllJoyn and MQTT are both open source projects for Internet of Things interoperability, both provide an event bus and a router/broker to connect devices. What is the difference? Are they compatible? Which standard should I use to implement my future-proof IoT device?
AllSeen Alliance's AllJoyn project is open source proximal IoT. It is usually a mesh topology.
MQTT is open source cloud IoT that works well on mobile and satellite networks. It is pub/sub with topics.
They are complementary, in fact IBM is working on a MQTT plug-in for AllJoyn's gateway agent.
You can read about that in AllJoyn Adds Human Touch to the Internet of Things. However, it seems that AllJoyn to be younger that MQTT, so for the second protocol is possible to found more documentation and frameworks.
Is there any hardware VoIP PBX that allows external software to subscribe on its events, determine incoming caller IDs (including GSM numbers that have been gateway-ed) and perform outbound voice calls via API?
Thanks!
There are many PBX's which support Computer Telephony Integration (CTI).
The most common standards to support are CSTA and JTAPI - if you google 'PBX supporting JTAPI' for example you should see several examples in the first few pages of results.
Any PBX supporting these standards will most likely meet your needs.
It would be worth your while looking at Asterisk based PBX's also in case these met your needs and allowed more scope for further development/features if required in the future. Many firms make Asterisk PBX's - the following link provides a good list:

I study the construction of mobile networks and began to study MVAS. But could not find a specific iinformation what protocols are used in the VAS or MVAS.
I understood that main protocol using SMS - it SMPP.
It would be great if someone made a list of the protocols used, or links where I could read more information about the protocols used.
There is such a list; it is published by 3GPP in specification TS 23.039.
3GPP (earlier ETSI) specified the GSM, UMTS and LTE systems, with standard protocols for most of the interfaces. They did not specify any standard protocol between Short Message Service Centres and external messaging servers though.
Instead, this was left open, and each SMSC developer specified their own protocol. An early and successful SMSC developer was an Irish company called Aldiscon, which was later taken over by Logica. They developed the Short Message Peer-to-Peer protocol (SMPP), and published it as an open standard, which is the reason why it's so widely used today.
Does anyone know of any resources that can give me an idea of how widely various JSRs are implemented?

Which phones support which spec
There are a few options none of them are complete :(
J2mePolish's db
Device Atlas
WURFL
Nokia, Sony-Ericsson,* providers websites.
This information isn't aggregated any where really but for JRS information I would say j2mepolish has the greatest source of this information with +- 1000 devices. Although Wurfl and DA have more devices they are mostly targeted and WAP+Mobile Web developers
JBenchmark is quite a substantial database of API compatibilities.
