Hi, I know that this has been discussed many times. Just want to get a clear answer. Is it possible to map inbound calls to a particular gateway based on IP address? Someone seems to claim that it's working. Others say no way. I tried to put context param in gateway section and no effect. This is in sip_profile gateway config. There were suggestions to just use context public, then send to its own context in dialplan. But that's not all the same. In asterisk world, the following section is sufficient in sip.conf. The system matches IP based SIP traffic first, then look for users with registration based. [providerA] type=peer qualify=yes context=provider_a host=1.2.3.4 disallow=all ; First disallow all codecs allow=ulaw ; Allow codecs in order of preference fromuser= dtmfmode=rfc2833 fromdomain=provider_a Richard
