My original macro worked just fine when the incoming number and the dialled extension matched, but this is only true for my LAN and is not generally true when using external SIP providers as the incoming extension is very often the user id of the account. https://minimal.org.uk/2007/11/21/asterisk-1471-take-2/ Wed, 21 Nov 2007 21:23:29 +0000 https://minimal.org.uk/2007/11/21/asterisk-1471-take-2/ Update: Thanks to Steve for pointing out that SayNumber (line 5 of 1471 below) is a bad idea: it works just fine in limited testing on my LAN, but when given a normal UK 11-digit number it seems to have some trouble trying to pronounce 01234 567 890 as 1 billion, 234 million, 567 thousand 890… Switching that command for SayDigits not only lets the function work, it also makes far, far more sense when listening to the result, too. https://minimal.org.uk/2007/11/21/asterisk-1471/ Wed, 21 Nov 2007 07:56:13 +0000 https://minimal.org.uk/2007/11/21/asterisk-1471/ Wanting to make my home Asterisk box a convergence point for VoIP and PSTN mans that I really wanted to have the “last number caller id” option that BT offer in the UK, but sadly the page on the Asterisk Wiki that mentions 1471 is no longer valid, so here’s my own implementation. It’s not 100% feature complete, but it does work in a comparable way to the PSTN version. https://minimal.org.uk/2007/10/03/nokia-n770-asterisk-and-google-talk/ Wed, 03 Oct 2007 13:23:14 +0000 https://minimal.org.uk/2007/10/03/nokia-n770-asterisk-and-google-talk/ I’ve wanted to get a VoIP application working on my N770 pretty much since day 1: the trouble is I’m rather picky… I want to be able to use it without pain from any WiFi point I happen to find myself at and I can’t use the N800 version of Skype, but that’s fine by me as I want to have some control over my datastream. It does however pretty much rule out most SIP-based solutions, as one-way audio is the best to hope for without control of NAT port forwarding (and that isn’t something hotels/coffee shops are going to have much truck with).
