I'm looking for any potential gotcha's on a planned SIP trunk integration. Current architecture uses a QSIG trunk between the two side-by-side systems to route calls between CM<->CIX. Planning to move the Toshiba 670 to new facility with Private WAN connectivity for transport between sites. The 670 has a SIP trunk capability, but that is documented as being used for SIP Service Provider connectivity. Seems like it should be easy to use a SIP trunk instead of PRI. Anyone done this? If so, please add comments regarding known compatibility issues. Not finding anything on CCO or Google searches.
Thanks for your thoughtful contributions.
