I need some experienced help. I'm using two SPA-841 phones and two SPA3000 units to run my asterisk system.

First problem, if I do SetCIDNum or fiddle with the caller ID in any way, it comes in as "asterisk" instead of the number. According to a doc I read, "asterisk" is asterisk's default for unknown. If I don't fiddle with it, it comes in fine, but I have my SPA3000 appending an A to the number, so if it comes in like that, I can't redial it.

Second problem, I'm having trouble picking the codec to use. 711u seems to require too much work from my phone at home (SPA3000 is at the office) and after about 5 minutes on the line, I can still hear the caller, (garbley though) but the caller can't hear me and I have to call them back. So I tried 729, and there's a whole lot of clicking on the line and the delay is pretty rough (less compression should make transmission faster). 726, the volume is low. Any tips/tricks for how I should make this work correctly for me?

Thanks.

How much bandwidth do you have at home? G.711 requires 80kbps in each direction to function properly. Others need less. Each CODEC requires about 16kbps of overhead on top of whatever the encoding rate is.

Also, if you have other devices competing for bandwidth, like FTP or gaming, they might be starving your SPA of the bandwidth it needs to work.
