[Asterisk-Users] Incoming SIP matching

[John Todd]

>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.
