I am trying to configure a Polycom 601 with an expansion module (side car) for 14 extensions. I see 12 configured but not the other 2 extensions. I have reg.1 - reg.14 configured in my 0004xxxxxxxreg.cfg file edited correctly. I have read in the documenetation that the max registration on a 601 is 6 per 601 or with side car 12. Is this a limitation of the phone or the trixbox? Is there a different solution that I should be using such as the buddies list? Is there another parameter that I should be tweaking in another file? Thanks in advance for your replies.
