For a quite old ToIP installation, i'm facing many issues, and requiring your skills.
The architecure is quite basic, two sites with tow CCME 4.0 with a sip trunk between them.
[IPPhones Site A]-----sccp----[CCME of site A]-----WAN (sip trunk)------[CCME of site B]---sccp---[IPPhones Site B]
- Is the RTP direct between IPPhones site A and IPPhones site B? or hairpining on the router?
- Some call between sites hanged out w/o any reason.. i don't know how to troubleshoot the SIP trunk... I didn't find any show sip trun status... help would be appreciated
- Some of the phones (7940) hang out w/o any reason, either with handsets or speakerphone... any idea (i troubleshoot a lot, but find nothing)? I heard about physical diseases on this phones, could you give me some infos?
I know i'm asking a lot, but i'm turning crazy, and i don't know if i'm underskills or if this installation is getting too old (one of the CF have to bee replaced last year because it reached the max R/W cycles!!!!)
