[Asterisk-Users] Incoming SIP matching

[Thomas B. Clark]

Incoming FWD calls from other FWD users, iaxtel, or via ipkall, need to 
have dtmfmode=rfc2833.  However, incoming FWD calls from the dialup 
access numbers (such as libretel) need to have dtmfmode=inband.  To 
solve this problem, I created a second FWD account and configured 
sip.conf as follows, in order to match the incoming number to the proper 
dtmfmode:

[fwd-rfc]
type=friend
secret=*****
host=dynamic
dtmfmode=rfc2833
username=76153
callerid="CLARK THOMAS B" <76153>

[fwd-inband]
type=friend
secret=*****
host=dynamic
dtmfmode=inband
username=244006
callerid="CLARK THOMAS B" <244006>

What I find is that, no matter what I change (for example, host-dynamic 
in order to prevent matching by IP address), I cannot make the incoming 
SIP calls match successfully. With the configuration above, all incoming 
calls use dtmfmode=rfc2833, but that could be because it's the default. 
  Either entry works correctly alone (with the other commented out.)

I found some discussion in the archives about incoming sip matching, but 
no patches.

Is there a better way to handle the two types of incoming FWD calls?  If 
not, is there something else I could change in order to make them match 
the correct section?  Any ideas would be appreciated.
