Minor modifications on the original patch to use ftdm_hunting_direction_t
everywhere instead of ftdm_direction_t or int
Patched-by: Marc Olivier Chouinard
* Rename option ringback-during-collect to immediate-ringback
* Allow regular ringback tone with immediate-ringback, not just a wav file
* Do not request full frame of data, just packet_len which is what we receive per IO interval
* Ignore user data when playing ringback tone
FTDM_SIGEVENT_UP was falling through to FTDM_SIGEVENT_PROGRESS_MEDIA, which
does (almost) the same, so no harm, but still fix it.

Portability fix for uClibc and other (linux) environments that lack execinfo.h.
ftdm_backtrace_walk() and related return FTDM_NOTIMPL and print a message
if backtraces are not available in the current environment.

Indicator in IAM message.
- ss7_iam_nature_connection_hex is the channel variable to carry
HEX value from/to IAM message
- X-FreeTDM-IAM-NATURE-CONN-HEX is the x-header string to carry
HEX value from/to sip invite message
- This IE is 8 bit hex, which turns into 2 chars
- Only Satellite indicator, Continuity check indicator, and Echo
control device indicator are supported. Spare value are not taken.
Spare value is always set to all zero.
- example:
To set 00010101 (bit H-A), set X-FreeTDM-IAM-NATURE-CONN-HEX string
value to 15 in the sip invite message to NSG.
When NSG send out sip invite, if the incoming IAM message comes with
Nature of Connection IE, NSG will put X-FreeTDM-IAM-NATURE-CONN-HEX
in the invite x-header. For example, if the IE value is 00001010 in
the IAM, NSG will send X-FreeTDM-IAM-NATURE-CONN-HEX with value string
of "0A".
- Two characters are madatory. "0A" must be specified rather than "A". If
invalid format or characters are found, this x-header will be ommited.
- Valid characters include 0-9, A-F, and a-f
Read the forward call indicator IE and print it into channel variable
ss7_iam_fwd_ind_hex. If this variable exists, put it in the x-header.
This implementation takes bits of A, CB, D, E, F, HG, I from the hex
value. Bits of KJ, L, P-M are not taken and set to 0.
The hex value is H-A-P-I, H is the highest bit to A, and next is P-I.
I is the lowest bit in the whole field, and H is the highest bit in
the whole field. Refer to Q.763 chapter 3.23.
IE's heximal value.
- add <action application="export" data="freetdm_iam_fwd_ind_HEX=2301"/>
to dialplan with expected hex value. If the outgoing ftdm channel's
forward indicator needs to be changed, "export" needs to be put in the
incoming channel's dialplan to set this variable value accordingly.
- this implementation takes bits of A, CB, D, E, F, HG, I from the hex
value. Bits of KJ, L, P-M are not taken from the hex.
- How to calculate hex value with wanted bits:
. the hex value is H-A-P-I, H is the highest bit to A, and next is P-I.
I is the lowest bit in the whole field, and H is the highest bit in
the whole field. Refer to Q.763 chapter 3.23.
. use a text pad to fill in the bits with 0 and 1. eventually fill all
the 16 bits
. copy the binary value into a calculator and convert it to hex
