[OpenSIPS-Users] infinite loop

[Sebastian Krueger]

Hi Bogdan,

yeah, something like that.

In my case it's

483 Too Many Hops

any idea why that might happen?

Also, I'm wondering if you anyone could help me out with these questions:

Does "uri" == "$ru"?
What does the "myself" resolve to?
Does "method" == "$rm"?
Is the "msg:len" variable meant to be "$cl"?

Any info is much appreciated.

Cheers, Sebastian.
