[asterisk-r2] Problems with OpenR2, Asterisk 1.4.24, Sangoma E1 Card and Axtel as Provider.

[Alvaro Parres]

Hi list:

	I have a issue on one of my asterisk servers with Sangoma E1 Card, OpenR2 and mfcr2 signaling.

	On a server that was working correctly and failed some days after, I attach to this email the logs of the error

	So I've two questions:

		1) Does any one have any idea of why this error?

		2) Does any have a Sangoma Card with Axtel that can share their configs so I can compare them ?

Thanks.
