Hi all.

FreeSWITCH Version 1.0.head (git-9ff8f53 2011-05-03 12-13-52 -0400)

I have problem with transfer channel to FS extension.

I send from external system to FS command as

   "SendMsg " + uniqueId + "\n" +
   "call-command: execute\n" +
   "execute-app-name: transfer\n" +
   "execute-app-arg: " + destination + "\n\n";

after ~70 correct transfer actions FS send BYE to my phone and send HANGUP_EVENT with cause EXCHANGE_ROUTING_ERROR to my system. (FS log attached)

from FS loggs:

2011-08-09 04:48:38.525293 [DEBUG] mod_sofia.c:457 Channel sofia/internal/1000@vkozak.starpoundtech.net hanging up, cause: EXCHANGE_ROUTING_ERROR
2011-08-09 04:48:38.525293 [DEBUG] mod_sofia.c:500 Sending BYE to sofia/internal/1000@vkozak.starpoundtech.net

what for does limitation of transfer operations exist?

how can I avoid this issue?

is't possible to increase number of hops for transfer command?
