A person who threatens, or harasses another person over the phone, but wouldn't have the courage to do it in person.
She called my house today, and cursed me out, and threatened to beat me up, but when I saw her in school earlier today, she couldn't look me in the eyes. She's a punk! She just a phone-thug!

back when their primary use was calling, it was like torture to go anywhere because every 5 seconds a random phone would ring. now that people use their cell phones mostly for texting and web browsing, life is better, though it's still slightly annoying to see everyone looking down at their phones.

*ring* *beep beep* *rrriiiinnnng*
random guy: hi
other guy: How's it going
me: crap cant you people turn off your cell phones for once do you realise how annoying they are?!!
2011
*complete silence*
me: aahhhhh finally...
guy looking up from phone: what'd you say?

Someone who attends a live music event and insists on filming the performance on their phone instead of enjoying the atmosphere. Exactly what these dipshits do with the footage after the event is unclear but it's likely it just sits on their phone, acting as a reminder of the performance they attended in person but largely watched via a 5 inch screen. The Phone Wanker is further characterised by the person filming the event with their phone in a vertical/portrait orientation, thus rendering the footage unusable for any purpose other than viewing it on their phone. Sadly all attempts to capture the event for prosperity (or perhaps bragging rights) are rendered useless anyway since the diminutive microphone on the phone is inadequate when faced with the venues high powered speaker stack.
I went to see Rag n Bone man in concert last week. Amazing gig but I was surrounded by Phone Wankers who insisted on filming it!

Teresa: Nuthin. Good.
John: ... That's good. What did you want to talk about?
Teresa: Idk.

to pretend your on the phone with/ texting someone while in public for either two reasons:
1. too look cool and like you have friends or
2. to avoid certain situations
reason number two is the most respectable one.

A person or friend who will call your cell phone to rescue you from an uncomfortable or otherwise undesireable conversation with someone else.
Thank god my phone goalie stepped in, because if I had to listen to one more story about how she named her cat "Pilates", I was going to pull my own arms off....

SIP - (Session Initiation Protocol) is a signaling protocol used to create, manage and terminate sessions in an IP based network. A session could be a simple two-way telephone call or it could be a collaborative multi-media conference session. This makes possible to implement services like voice-enriched e-commerce, web page click-to-dial or Instant Messaging with buddy lists in an IP based environment. SIP has been the choice for services related to Voice over IP (VoIP) in the recent past. It is a standard (RFC 3261) put forward by Internet Engineering Task Force (IETF). SIP is still growing and being modified to take into account all relevant features as the technology expands and evolves. But it should be noted that the job of SIP is limited to only the setup and control of sessions. The details of the data exchange within a session e.g. the encoding or codec related to an audio/video media is not controlled by SIP and is taken care of by other protocols.
