This invention relates to the allocation of communication channels. The idea of the invention is to form different channel groups with a group specific identifier in the IP network side of a network element between a PSTN and IP network. Each group represents a certain type of channel, for example, alarm calls, area codes, companies, etc. The PSTN network side of the net-work element forms a single group due to the need of a unique SPC. A channel is associated with the right group according to the information of the calling or called party in the call signaling, such as an E.164 number or a signaling IP address. The information is linked to the group identifier. |
