I have a 1.2.4 * box with two HFC modems using chan_modem_i4l and several SIP phones and ATA's. We have a terrible delay on calls between the PSTN (isdn BRI) and the SIP phones. All internal calls are fine. My first thought was that the transcoding could cause the delay but all of the SIP phones default to ulaw so there should not be any transcoding needed. I also checked the load on the server and it is well below 10% cpu utilisation and load average of below 1.
Is there some form of jitter buffering going on? Perhaps the echo cancelling (I assume there is some) is adding a significant delay? Perhaps try turning it off temporarily. It seems likely to be related to chan_modem_i4l if your internal calls are all okay.
