Anyone see this before?
I have a main Asterisk box 11.4 connected to Windstream via SIP trunks in my
colo.
So as a did comes in they are routed to appropriate customers, in this case
another asterisk 11.4 box.
All is working well with the exception of DTMF. Losing the last digits so say
someone hits 123... on the customer box I only get 12
This is the weird part, it only happens on 1 DID. If I point another DID from
the same carrier to the customer it works. Both the main asterisk box and
customer are running real IP's (no nat)
Did a test and routed the DID to a IVR on my main system and I see the correct
DTMF, so somewhere in the process of local bridging DTMF is getting messed up.
Both carrier and customer were set to RFC2833.
Upgraded Asterisk 11.4 to 11.5 on both systems same issue.
Changed customer to DTMF info and it fixed it.
Could line level of a DID cause this? I researched this a lot and find
conflicting answers.
How does asterisk local bridge calls, does it affect the line levels. My
understanding of RFC2833 is that line level issues should not affect it.
