Summary:                    [patch] chan_sip does not support the maddr
attribute in Via headers
Description: 
I recently connected Asterisk with a badly configured Nortel CS2K, which
sends me the following Via header:

Via: SIP/2.0/UDP
CS2KSSTEMAG:5060;maddr=213.60.204.48;branch=z9hG4bK-142abd7-ec6f41f2-4aeebdaf

CS2KSSTEMAG not being a valid DNS entry, the reply is never sent (Asterisk
blocks trying to resolve the name). Even tho it is a configuration error,
maddr should be used as reply address.

The attached patch fixes the issue in 1.4.23.1
