There are a couple of old E1 telphony protocols that Wireshark has dissectors for:-

Q.931

Would it be possible for someone to add them to the "Voip Calls" display?

I realise that they are not strictly IP, but it would be very handy to be able to use that type of CDR display to identify the calls in a trace from an E1 link (captured via a 3rd part analyser") and filter on them. These are only a D channel decode and hence there would be no RTP streams and so the RTP player would need to be greyed out.

I don't see why we couldn't add such a feature, although it might be better under another menu called something along the lines of TDM under the telephony menu. So the information is already handled by existing dissectors and you just need them added to a nice list like VoIP calls?
