Select outgoing trunk

Hi there,
I want a specific SIP-Phone to place all calls over trunk1 and another SIP-Phone to place all calls over trunk2. How can I achieve this?



This can be accomplished using the Custom Contexts module - see

Alternately, if you trust the users of those extensions, just give them each a dialing code prefix for the respective trunk, then strip the prefix before sending it to the provider. For example if they dial 9+number it would go to trunk 1, while 8+number would go to trunk 2 (each would actually select an outgoing route, which then uses the appropriate trunk(s)).
