multiple iaxmodems registers on wrong port

[Alessan]

Hi,

I'm getting strange behavoir with multiple modems, when i start iaxmodem i got on asterisk console:

-- Registered IAX2 '9902' (AUTHENTICATED) at 127.0.0.1:4575
-- Registered IAX2 '9902' (AUTHENTICATED) at 127.0.0.1:4572
-- Registered IAX2 '9907' (AUTHENTICATED) at 127.0.0.1:4573
-- Registered IAX2 '9907' (AUTHENTICATED) at 127.0.0.1:4577
-- Registered IAX2 '9910' (AUTHENTICATED) at 127.0.0.1:4580
-- Registered IAX2 '9909' (AUTHENTICATED) at 127.0.0.1:4579

Some modems registered on another modem port and inmedialy registered on right port, droping other iaxmodem register.

How are you starting iaxmodem? Does this happen if you start iaxmodems with non-daemon mode? Does the problem happen only with some of the iaxmodems? Or does it happen to all of them even randomly?

[Alessan]

Sorry but late response,

I can't be sure, but seems randomly.

In non-daemon mode seems happened less.

Finally I work with static config without register and all works fine. I go to try to get some packet captures on daemon and non-deamon mode to see if this is a asterisk side problem or iaxmodem side.

Thanks
