Dropping calls ?= transfers / 3ways

[Plat]

Having an issue with our overseas room, not sure if its bandwidth related or now because we know they have sub par bandwidth there comparable to like 56k .. not that bad but under a meg up & down. When they do a transfer and park the call to deliver to our verifiers & or closers in the states, the call gets dropped and there is just dead air on the line. I do believe they are using a g724 codec there while we use g711ulaw not sure if thats the issue or not either. I'm just throwing out things to try and figure this out becuase we are dropping calls left and right. We're getting them to install some fiber network and up their bandwidth this week im just not sure if thats the main cause or if asterisk doesn't like 3way transfers that much.

Asterisk is unaware of 3way transfers. It is only aware of calls. You will need to determine the cause of the termination of the call. One end of the call is cancelling the call or the call is breaking. The logs will show a termination request, and the side that requested it ... and if the side is your asterisk server they will show a cause. If the call is broken, of course, this will show as well but not quite as clearly in some cases.

Your side cannot use a different codec than their side (it does not work that way). Your agent may use g729 while the prospect leg of the call may use ulaw, but the asterisk server in the middle of that will use BOTH (g729 while communicating with the g729 agent and ulaw while communicating with the carrier). This rarely has anything to do with a dropped call, but can cause a "handshake error" if something is configured improperly (and kill the call).

You did not state whether this is a new install or a fresh problem on an old system. Nor did you mention whether it affects all agents, specific agents, or groups of agents.
