Dear Friends,
We have a D-Link DVX-2004 with Asterisk 1.4.21.2 with 4 Port and a Server with Elastix 2.5.0 X64Bit
now we want to Migrate all our calls (incoming & out coming) from old asterisk to new Elastix
how can i trunk between this 2 device?
Even though Asterisk 1.4 is obsolete, it supports a wide range of channel types. Elastix is based on Asterisk so presumably supports them as well. You can use SIP, IAX, H.323, ISDN, or even analogue (with some loss of signalling).
It looks like the online version of the book that corresponds to Asterisk 1.4 is still available at cdn.oreillystatic.com/books/9780596510480.pdf
Also note that General forums are discussion forums, not support ones.
