hi,
i know what u mean, and for it I have analysed the src code.
If I’m not wrong, you can’t specify the peer port in any context definition.
the only place to override the default port 5060 is the registration string.
In the meanwhile I’ve opened a bug report, marking it as a “tweaking” issue. However, I hope they will consider it at least as a feature request: I’m developing VoiceOne (www.voiceone.it), a GUI based on the Asterisk Realtime Architecture, and “register => 2345:password@sip_proxy” is the only way to fully use the power of Realtime.
