Hi, I have 2 * boxes linked via an IAX2 trunk. They seem to work fine for the better part but from time to time calls are dropped. What I noticed is the LAG value when doing a IAX2 SHOW CHANNELS command from CLI is off. Both boxes are * 1.0.7 , the interesting part is the * box on the remote side shows Lag of 00000ms while the local side shows Lags of 00020 or more. This lag seems to increase as the call progresses as well.
Here is an example:
pbxCLI> iax2 show channels
Channel Peer Username ID (Lo/Rem) Seq (Tx/Rx) Lag Jitter JitBuf Format
IAX2/trunkmain-peer/1 xxx.xxx.xxx.xxx trunkremote 00001/00002 00162/00163 00027ms 0001ms 0000ms gsm

Anyone seen this before? Is there a workaround or fix?
