[Asterisk-Users] Issue with IAXy in Canada?

[Obaid Siddiqui]

I tested traceroute and Iaxping with list member  John Cianfarani
<jcianfarani at rogers.com>, who is Rogers Cable user. We found out that it was
not a port blocking problem, rather it was failure of IAXy to get dhcp
address from the router.

Thanks for all who contributed especially John Cianfarani.

Obaid.
