Hi,
For 2 weeks now I have been experiencing the same crazy problem in two different customers. One has a 403V1 3.2.61 and the other has a 500 4.0.14. One telephone in each site (a 5420 in the first and a 5410 in the second) don't give a proper dial tone when picking up the handset. Both give, instead of a continuous sound, a sound that stops and starts and stops and starts etc. If you press 9 to access an outside line everything works as it should. Generally speaking both phones seem to be working perfectly except for the dial tone. Both phones have been upgraded to their system's corresponding version. I think the problem is with the ext. but I cannot find the why. Even a reboot doesn't help. Any ideas anyone?
Thanks
