Aastra 560M Sidecart BLF issue

[Entranced]

I have 4 Aastra 560M modules connected to Aastra 57i phones. I have manually added 60 users/entries as blfxfer to the 57iMAC.cfg that resides in /tftpboot.

Here is the sample:
expmod1 key1 type: blfxfer
expmod1 key1 label: Jack
expmod1 key1 value: 1122
...
expmod1 key60 type: blfxfer
expmod1 key60 label: Zack
expmod1 key60 value: 1266

The 560M is displaying all the users that I have added to the .cfg, but the last 10 users have "?" next to their name. Pretty much entries 1-50 are working properly (with the red light and telephone icon next to them), but 51-60 are not showing any type of activity (just the "?").

Is there any type of limitation in the module/phone itself, or there is some setting in Asterisk that needs to be adjusted ?

I have installed the latest (2.4.1) firmware on the 57i phone and also used previous 2 firmware releases with the same result.

Any ideas would be appreciated.

50 is the maximum that these units can monitor via blf.... If I recall correctly Aastra changed this in their firmware a while back due to memory leaks.... If you ask me this was a bandaid and not a fix... This is one area that they really need to improve on as they promote being able to link multiple 560's together (but what's the use if you locked at 50 )....

Thanks for quick reply.
I wasn't aware of this limitation. I guess I won't be purchasing any more 560M sidecarts until this problem is resolved. I was thinking about adding another 560M, since I have more than 60 users at the office. I will have to wait and as far as the existing 60 extensions, I will need to prioritize the BLF awareness.

Xml Blf ?

I read somewhere that someone had developed an XML BLF type application that would work beyond the 50 limit. Anyone know anything about this?
